v2.3    87/09/20  21:36:52  garyp
        Make default reject file /dev/null.  Report count of lines
        rejected, unless reject file specified.

v2.2    87/09/15  17:33:33  garyp
        Fix bug that caused dump when parm was null.  Changed mkname so
        that the path is removed from the input filename.  Added #$
        substitution parameter, to correctly split mailboxes.  Changed
        the default pattern for -m to use #$ instead of #7.

v2.1    87/09/15  00:20:07  garyp
        New release of slice, now supports substitution parameters.
        Use of %s and %d replaced by #f and #n respectively.
        Parameters #1, #2, ... #9 are replaced by tokens from the
        matched line.  Printf-style format (e.g. %02d) may immediately
        follow any substitution.

v1.12   87/09/10  17:05:04  garyp
        Reject file now added.

v1.11   87/09/08  23:53:29  garyp
        Add features "+<filename>" and "@"

v1.10   87/02/12  10:32:50  garyp
        Minor revision to Sys V changes Added #define match() to reduce
        number of #ifndef USG Added some comments

v1.9    87/02/09  10:10:27  garyp
        Revisions to support System V regular expression routines.
        Provided by Jon A. Tankersley.

v1.8    86/12/12  22:28:40  garyp
        Add -x and -a options.  Improve semantic checking.  Fix -n
        (wasn't working -- caused core dump).

v1.7    86/12/12  11:54:56  garyp
        Fix problem with multiple '+' formats Switch from 'w' to 'a'
        (append) access for output files.

v1.6    86/12/11  21:18:08  garyp
        Cleaned up error status codes.  Allowed '+' format to designate
        stdout.

v1.5    86/12/11  17:29:25  garyp
        New improved mailsplit with lots of features.  Renamed slice.

v1.4    86/12/09  17:03:05  garyp
        First parameter is now either -m, for mailbox pattern, or -s,
        for shell pattern, or -n for line count split, or a user
        specified pattern (not starting with '-').  These options
        replace -p.  The default output filename is now "%s:%03d" where
        %s is the input filename.

v1.3    86/12/09  12:57:49  garyp
        Fixed search for %d.  All forms now allowed.  Only %s allowed,
        though (no other form seems useful anyway).

v1.2    86/12/09  12:10:09  garyp
        Changed to allow output pattern to contain %s to represent
        input filename.  However, code only doe exact match on %d and
        %s.  It should do a pattern match to allow things like %6d.

v1.1    86/12/08  21:08:12  garyp
        date and time created 86/12/08 21:08:12 by garyp
