Log message:
lang/nawk: downgrade to 20230909.

Partially revert previous commit, by downgrading the package to the
most recent release tag supporting ASCII encoded input files (and
processing strings as sequences of bytes).
This is needed by security/mozilla-rootcerts and likely other packages;
see https://mail-index.netbsd.org/tech-pkg/2023/09/17/msg028190.html.

This version incorporates all the changes described in the FIXES file up
to 2023-09-09, minus support for UTF-8 and comma-separated values (CSV)
input.

Log message:
lang/nawk: update to release 20230911

This release marks the official 2nd edition of the AWK programming
language!

# CHANGES (since 20220122)

Sep 11, 2023:
	Added --csv option to enable processing of comma-separated
	values inputs.  When --csv is enabled, fields are separated
	by commas, fields may be quoted with " double quotes, fields
	may contain embedded newlines.

	If no explicit separator argument is provided, split() uses
	the setting of --csv to determine how fields are split.

	Strings may now contain UTF-8 code points (not necessarily
	characters).  Functions that operate on characters, like
	length, substr, index, match, etc., use UTF-8, so the length
	of a string of 3 emojis is 3, not 12 as it would be if bytes
	were counted.

	Regular expressions are processes as UTF-8.

	Unicode literals can be written as \u followed by one
	to eight hexadecimal digits.  These may appear in strings and
	regular expressions.

Sep 06, 2023:
	Fix edge case where FS is changed on commandline. Thanks to
	Gordon Shephard and Miguel Pineiro Jr.

	Fix regular expression clobbering in the lexer, where lexer does
	not make a copy of regexp literals. also makedfa memory leaks have
	been plugged. Thanks to Miguel Pineiro Jr.

Dec 15, 2022:
	Force hex escapes in strings to be no more than two characters,
	as they already are in regular expressions. This brings internal
	consistency, as well as consistency with gawk. Thanks to
	Arnold Robbins.

Sep 12, 2022:
	adjbuf minlen error (cannot be 0) in cat, resulting in NULL pbuf.
	discovered by todd miller. also use-after-free issue with
	tempfree in cat, thanks to Miguel Pineiro Jr and valgrind.

Aug 30, 2022:
	Various leaks and use-after-free issues plugged/fixed.
	Thanks to Miguel Pineiro Jr. <mpj@pineiro.cc>.

May 23, 2022:
	Memory leak when assigning a string to some of the built-in
	variables. allocated string erroneously marked DONTFREE.
	Thanks to Miguel Pineiro Jr. <mpj@pineiro.cc>.

Mar 14, 2022:
	Historic bug: command-line "name=value" assignment had been
	truncating its entry in ARGV. (circa 1989) Thanks to
	Miguel Pineiro Jr. <mpj@pineiro.cc>.

Mar 3, 2022:
	Fixed file management memory leak that appears to have been
	there since the files array was first initialized with stdin,
	stdout, and stderr (circa 1992). Thanks to Miguel Pineiro Jr.
	<mpj@pineiro.cc>.

	with awkgram.tab.* and simplify definition of YACC.

	with awkgram.tab.h.

	With scalpel, tweasers, magnifying glass and bated breath,
	borrow code from the NetBSD version of nawk to fix the years-old
	bug whereby decrementing the value of NF did not change the
	record.

	* lib.c (fldbld): Set donerec to 1 when done.

	* tran.c (setfval): Normalize negative zero to positive zero.
	If setting NF, clear donerec and call setlastfld().
	(setsval): Remove call to save_old_OFS().  If setting OFS, call
	recbld(). If setting NF, clear donerec and call setlastfld().

	As part of the process, revert OFS-related changes of 2018-05-22:

	* regdir/T.misc: Revise test to match fixed code.
	* run.c (format): Increase size of buffer used for %a test. (Unrelated
	to NF or OFS, but fixes a compiler complaint.)

	* regdir/beebe.tar: Fix longwrds.ok so that the test will pass.

	Fix nawk so that [[:blank:]] only matches space and tab instead
	of any whitespace character, originally made May 10, 2018.

2018-05-22         Arnold D. Robbins     <arnold@skeeve.com>

Log message:
Update to 20121220

* Works fine under Debian GNU/Linux 7.4, NetBSD/amd64 6.99.36
* Merge pkgsrc specific changes

Changelog:
Dec 20, 2012:
	fiddled makefile to get correct yacc and bison flags.  pick yacc
	(linux) or bison (mac) as necessary.

	added  __attribute__((__noreturn__)) to a couple of lines in
	proto.h, to silence someone's enthusiastic checker.

	fixed obscure call by value bug in split(a[1],a) reported on
	9fans.  the management of temporary values is just a mess; i
	took a shortcut by making an extra string copy.  thanks
	to paul patience and arnold robbins for passing it on and for
	proposed patches.

	tiny fiddle in setfval to eliminate -0 results in T.expr, which
	has irritated me for 20+ years.

Aug 10, 2011:
	another fix to avoid core dump with delete(ARGV); again, many thanks
	to ruslan ermilov.

Aug 7, 2011:
	split(s, a, //) now behaves the same as split(s, a, "")

Jun 12, 2011:
	/pat/, \n /pat/ {...} is now legal, though bad style to use.

	added checks to new -v code that permits -vnospace; thanks to
	ruslan ermilov for spotting this and providing the patch.

	removed fixed limit on number of open files; thanks to aleksey
	cheusov and christos zoulos.

	fixed day 1 bug that resurrected deleted elements of ARGV when
	used as filenames (in lib.c).

	minor type fiddles to make gcc -Wall -pedantic happier (but not
	totally so); turned on -fno-strict-aliasing in makefile.

May 6, 2011:
	added #ifdef for isblank.
	now allows -ffoo as well as -f foo arguments.
	(thanks, ruslan)

May 1, 2011:
	after advice from todd miller, kevin lo, ruslan ermilov,
	and arnold robbins, changed srand() to return the previous
	seed (which is 1 on the first call of srand).  the seed is
	an Awkfloat internally though converted to unsigned int to
	pass to the library srand().  thanks, everyone.

	fixed a subtle (and i hope low-probability) overflow error
	in fldbld, by adding space for one extra \0.  thanks to
	robert bassett for spotting this one and providing a fix.

	removed the files related to compilation on windows.  i no
	longer have anything like a current windows environment, so
	i can't test any of it.

May 23, 2010:
	fixed long-standing overflow bug in run.c; many thanks to
	nelson beebe for spotting it and providing the fix.

	fixed bug that didn't parse -vd=1 properly; thanks to santiago
	vila for spotting it.

Feb 8, 2010:
	i give up.  replaced isblank with isspace in b.c; there are
	no consistent header files.

Nov 26, 2009:
	fixed a long-standing issue with when FS takes effect.  a
	change to FS is now noticed immediately for subsequent splits.

	changed the name getline() to awkgetline() to avoid yet another
	name conflict somewhere.

Feb 11, 2009:
	temporarily for now defined HAS_ISBLANK, since that seems to
	be the best way through the thicket.  isblank arrived in C99,
	but seems to be arriving at different systems at different
	times.

Oct 8, 2008:
	fixed typo in b.c that set tmpvec wrongly.  no one had ever
	run into the problem, apparently.  thanks to alistair crooks.

Oct 23, 2007:
	minor fix in lib.c: increase inputFS to 100, change malloc
	for fields to n+1.

	fixed memory fault caused by out of order test in setsval.

	thanks to david o'brien, freebsd, for both fixes.

May 1, 2007:
	fiddle in makefile to fix for BSD make; thanks to igor sobrado.

Mar 31, 2007:
	fixed some null pointer refs calling adjbuf.

Feb 21, 2007:
	fixed a bug in matching the null RE in sub and gsub.  thanks to al aho
	who actually did the fix (in b.c), and to wolfgang seeberg for finding
	it and providing a very compact test case.

	fixed quotation in b.c; thanks to Hal Pratt and the Princeton Dante
	Project.

	removed some no-effect asserts in run.c.

	fiddled maketab.c to not complain about bison-generated values.

	removed the obsolete -V argument; fixed --version to print the
	version and exit.

	fixed wording and an outright error in the usage message; thanks to igor
	sobrado and jason mcintyre.

	fixed a bug in -d that caused core dump if no program followed.

Jan 1, 2007:
	dropped mac.code from makefile; there are few non-MacOSX
	mac's these days.

Jan 17, 2006:
	system() not flagged as unsafe in the unadvertised -safe option.
	found it while enhancing tests before shipping the ;login: article.
	practice what you preach.

	removed the 9-years-obsolete -mr and -mf flags.

	added -version and --version options.

	core dump on linux with BEGIN {nextfile}, now fixed.

	removed some #ifdef's in run.c and lex.c that appear to no
	longer be necessary.
