Log Message:
1.2.4	2013-07-01 (released)

	2013-06-28
	* Fix three crashes in command line and environment variable parsers
	  that caused NULL pointer dereferences with long option variants
	  of bogofilter --syslog-tag, or bogoutil --timestamp-date, or when
	  bogotune -M<file> cannot derive the bogofilter directory.
	  Reported by Alexandre Rebert, found with Mayhem tool.

	* Add getopt_long_chk(), a getopt_long variant that checks if the
	  overlapping short and long options agree on whether their argument
	  is not required, mandatory, or optional.  If they disagree, the
	  program aborts.

	* Fix a crash in command line parser that causes a NULL pointer
	  dereference when --db-cachesize is used without argument.
	  Found with getopt_long_chk().

	2013-01-20
	* Change lexer API/ABI a bit so as to work with flex 2.5.36 generated
	  lexers (for instance, on Fedora 18 "Spherical Cow") that flip the
	  type of yyleng from int to size_t. We use a signed long internally.

	2012-12-30
	* The bogofilter project was updated to the new SourceForge.net
	  platform. This has caused the URLs to change. Use one of these
	  commands for a read-only checkout:
	  svn checkout svn://svn.code.sf.net/p/bogofilter/code/trunk bogofilter
	  svn checkout http://svn.code.sf.net/p/bogofilter/code/trunk bogofilter

	  And developers would use, replacing joe by their sf.net login:
	  svn checkout --username=joe \ 
svn+ssh://m-a@svn.code.sf.net/p/bogofilter/code/trunk bogofilter

	2012-12-03
	* Add bogofilter-SA-2012-01 (CVE-2012-5468).
	* Fix XML form of Bulgarian FAQ so that it validates;
	  and validate XHTML at build time.
	* Mark Berkeley DB 5.2.42 and 5.3.21 supported.
