Hard set the version number, instead of relying on no-longer-expanded
CVS keywords.  Update the home page accordingly, and along the way
also switch to ISO 8601 style dates for the Release History section.

Add the copyright notice that the 'cvs2cl.pl' script has (oops) been
missing for 22 years, replacing the now-unused CVS keywords that Git
doesn't support anyway.

  (delta_check): Oops, follow up to r2.69 with a second typo fix.  D'oh.

  (delta_check): Fix typo introduced in r2.65 that caused --delta to
    effectively ignore TO_TAG (that is, 'cvs2cl.pl --delta FROM:TO'
    would also display any changes between TO and HEAD).

   Hello bean people!

   First of all, thanks for the script without which cvs log is basically
   useless. However, I wasn't able to run the script properly with
   cygwin/cvsnt. Cygwin looked for the script in "/cygdrive/c/Program
   Files/cvsnt/", and Perl couldn't handle the space in "Program Files"
   (classic issue it seems), resulting in the following error message:

   Can't open perl script "/cygdrive/c/Program": No such file or
   directory

   I asked about this on the cygwin mailing list (see thread at
   http://www.mail-archive.com/cygwin@cygwin.com/index.html#87229) and
   was told to put the $0 on the second line (exec perl) in quotes, which
   works fine.

   I don't know if this would break script execution on other systems. If
   so, you could mention this issue on the web site. If not, please fix!
   :)

   Thanks, Andreas

  (FSF_Output): New variable.
  (parse_options): Set it, check that it's not used with --accum.
  (POD documentation): Document inter-option restrictions.

  stop referring to the $pw->name field.

His bug report said "there is a small bug in cvs2cl.pl in
read_date_author_and_state() if someone has an entry in the
/etc/passwd file but an empty gecos field.".

   The same cvs2cl from CVS HEAD.

   I would like to execute it with full output path, e.g.

   "perl cvs2cl.pl --file D:\MyProjects\Project1\reports\ChangeLog"

   when output is not distributed, everything is groupped in directory
   "./" and finally script is trying to create file with the path
   ./D:\MyProjects\Project1\reports\ChangeLog/cvs2clXXXX.tmp" and
   fails.  Looks like the code is fixing this issue only for unixes
   where full path is started with '/' however on windows full path
   starts with drive and the fix is not working.

  (read_changelog): Don't fork on Windows, just open a subcommand.

   I checkouted revision 2.59 from CVS and it does not work under
   Windows using Active Perl 5.6.1.

   The previous version I use was 2.53 and it work fine. The
   difference I noticed is in read_changelog() - new version uses
   fork(). I think fork is not need on windows, so the patch is below:

  (parse_options): Allow period in regexp that matches the tag
    arguments to the --delta option.

  thanking Martyn Pearce.

header line of a ChangeLog entry to allow for optional day of week.

This fixes the bug whereby the --accum option would not work when the
existing ChangeLog was generated with the -w (--day-of-week) option.
