Update slrn to 1.0.1.
Based on PR pkg/49129 by Leonardo Taccari.

Changes since 1.0.0
1. An issue with the wrap_width variable was fixed.

Changes since 0.9.9p1
1. src/charset.c: Avoid using CODESET if it is not defined.
2. doc/slrn.1: Remove blank line at top of file. (Ignatios Souvatzis)
3. src/Makefile.in: /bin/sh on solaris does not like empty lists in a
   for loop causing make install to fail.  Workaround added
   (Petr Sumbera).
4. src/mime.c: rewrote much of the email address encoding/decoding so
   that only comment fields in email addresses are encoded/decoded.
   slrn is also smarted in encoding/decoding other headers (based on
   patch from Robert Grimm).
5. autoconf/Makefile.in: Added dependencies such that if the
   Makefile.in and config.in files have been modified, the user is
   told to re-run the configure script.
6. Updated the copyright years to 2009.
7. src/mime.c: Omit the mime headers if the content is pure 7bit.
   Also, if mime-headers already exist, do not add append additional
   ones.
8. configure: Added the configuration option --with-non-gnu-iconv that
   can be used to indicate that local version of iconv is not
   compatible with GNU iconv (Piotr 'aniou' Meyer).
9. src/charset.c: Upon failure, slrn_test_convert_lines will return the line
   that caused it to fail.
10. src/charset.c: If the --debug option is given, slrn will write the
    strings that iconv failed to convert to the log file.
11. src/post.c: Skip long line checks between verbatim marks. (Robert
    Grimm).
12. src/nntplib.h: Removed duplicate declarations of nntp_server_cmd
    and nntp_server_vcmd. (Li Hong).
13. src/decode.c: If an output file already exists, create a new one
    by appending an integer to the name.
14. src/slrn.c: work around a SLang_getkey bug that arises when the
    underlying read system call is interrupted, and the interrupt hook
    creates a different read descriptor.
15. src/misc.c: All error messages (including slang tracebacks) are
    logged to the --debug output file.
16. src/art.c,etc: If an article has invalid headers, clear the error
    but give the article an initial score of -1000.  This number may
    be customized using the "invalid_header_score" variable.
17. src/mime.c: In slrn_mime_process_article, decode headers even if
    Content-Type is not understood and metamail is needed.
18. src/art.c: Avoid a buffer overflow when reconstructing huge
    threads.  Thanks to Robert Grimm for finding the problem.
19. src/version.c: %d format was used to print a long integer.
20. src/nntplib.c: slrn user "narke" discovered that his server will
    disconnect if an attempt is made to post an empty body.  slrn does
    this after authenticating with the server to verify that posting
    is possible.  As a work-around, the response comment from the
    AUTHINFO command is parsed.
21. src/sltcp.c: Add support for gnutls logging functions.
22. src/chkslang.c: Fixed a sscanf format issue involving long long
    integers.
23. src/sltcp.c: Change 21 needed #ifdef SLTCP_HAS_GNUTLS_SUPPORT.
24. src/nntplib.c: A comparison in #20 should have used != instead of
    ==.
25. doc/slrn.rc: "utf8" changed to "utf-8" (Thomas Wiegner).
26. src/art_misc.c: Increased the search range for a pgp signature.
27. src/misc.c: The rline_update callback function was not handling
    the case where no prompt (prompt==NULL) was associated with the
    readline object.  (M. G. Berberich)
28. src/vfile.c: Add explicit void* to char* cast for better C++
    compliance.
29. doc/tm/: Updated the Makefile and rebuilt the docs
30. src/interp.c, art.c: Added support for an optional argument to the
    replace_article function that dictates if the article should be
    mime processed.
31. src/*: Updated copyright year and trimmed extra whitespace.
32. macros/mime.sl: Added initial support for multipart mime messages.
    See macros/mime.sl for additional information.
33. macros/mime.sl;src/*.c: More support for processing multipart mime
    messages, including the ability to save/view the various parts of
    a message.
34. src/misc.c:generic_read_input: If point is negative, regard it as
    an offset from the end of the string.  Changes were also made to
    the callers of this function accordingly.
35. macros/mailcap.sl: If an executable does not exist on the search
    path, skip the mailcap entry.
36. src/interp.c: Added "replace_cooked_article", which is like
    to "replace_article", but does not affect the raw lines.  mime.sl
    was updated to use this.
37. macros/mime.sl: Added an option to the browse menu that permits
    the full raw article to be viewed.
38. macros/mime.sl: Added a more informative message when a mime
    article is encountered.
39. src/mime.c: A couple of strncmp calls used the wrong length (Patched
    by Thomas Wiegner).
40. macros/mime.sl: The boundary subkeyword was not being detected in a
    case-insensitive way.  Also the wrong filename was mentioned in
    the usage comments. (Christian Ebert)
41. macros/mime.sl: Add an option to view all parts of a mime
    multipart message.
42. Added a top-level win32 directory containing scripts for building
    slrn using MinGW on a Windows system.  See doc/INSTALL.w32 for
    details.
43. src/*.c: Various win32-specific tweaks to avoid some warnings
    generated by MinGW's gcc.
44. win32/msinstall.sl: Use $prefix/share/man instead of $prefix/man
    for the directory where man pages are installed.
45. doc/THANKS updated.
46. updated autoconf/config.guess and autoconf/config.sub
47. doc/THANKS rearranged.
48. src/art_misc.c: New config variable: "wrap_width", which sets the
    width that will trigger wrapping.
49. doc/: Updated txt docs from slrn doc project's svn repos.
50. Version 1.0 released [Dec 21, 2012].
