       Originally, `%s' was the only valid string.  The string that
       was substituted for it was:

         <repository-name> <file1> <file2> <file3> ...

       Each file was either a new directory/import (T_TITLE), or a
       added (T_ADDED), modified (T_MODIFIED), or removed (T_REMOVED)
       file.

       It is desirable to preserve that behavior so lots of commitlog
       scripts won't die when they get this new code.  At the same
       time, we'd like to pass other information about the files (like
       version numbers, statuses, or checkin times).

       The solution is to allow a format string that allows us to
       specify those other pieces of information.  The format string
       will be composed of `%' followed by a single format character,
       or followed by a set of format characters surrounded by `{' and
       `}' as separators.  The format characters are:

         s = file name
	 V = old version number (pre-checkin)
	 v = new version number (post-checkin)

       For example, valid format strings are:

         %{}
	 %s
	 %{s}
	 %{sVv}

       There's no reason that more items couldn't be added (like
       modification date or file status [added, modified, updated,
       etc.]) -- the code modifications would be minimal (logmsg.c
       (title_proc) and commit.c (check_fileproc)).

       The output will be a string of tokens separated by spaces.  For
       backwards compatibility, the the first token will be the
       repository name.  The rest of the tokens will be
       comma-delimited lists of the information requested in the
       format string.  For example, if `/u/src/master' is the
       repository, `%{sVv}' is the format string, and three files
       (ChangeLog, Makefile, foo.c) were modified, the output might
       be:

         /u/src/master ChangeLog,1.1,1.2 Makefile,1.3,1.4 foo.c,1.12,1.13

       Why this duplicates the old behavior when the format string is
       `%s' is left as an exercise for the reader. */
