Update shells/osh

Add new maintainer. Thank you J.A.
The following is from PR #40006:

I would like to maintain this package if that is acceptable.
Thus, I added myself as MAINTAINER.

Changed files: DESCR, Makefile, PLIST, distinfo

Changes between osh-20080629 and osh-20081122 which affect the osh
package on the various pkgsrc platforms are described below.

------------------------------------------------------------------------
[osh-20081122]:
mkconfig:
        * Added a case for DragonFly BSD (uname -s == DragonFly).

osh.c:
        * Fixed a bug introduced in osh-20061230 where the shell
          incorrectly handles an unescaped terminating backslash (\)
          character at the end of string when the shell is invoked as
          `osh -c string'.  In this case, the terminating backslash
          causes the shell to incorrectly read from the standard input
          at the end of string.
          For example:

                % osh -c 'echo Hello\'
                to\
                you!
                Hello to you!

          This example should instead do nothing and exit w/ a zero
          status.  For `osh -c string', an unescaped terminating
          backslash should effectively turn string into a no-op.
          Now, it behaves as expected.

------------------------------------------------------------------------
[osh-20081026]:
Makefile:
        * Changed the "oshall" target to only build osh since the fd2,
          goto, and if utilities are now built into the shell.

        * Changed the "install-oshall" target to only install osh and
          its manual pages.  This includes the fd2.1, goto.1, and if.1
          manual pages since they are not fully documented elsewhere.

osh.c:
        * Renamed cmd_index() to cmd_lookup(), and changed the algorithm
          from a linear search to a binary search.

        * Added a base reallocation multiplier to glob() to reduce the
          number of realloc()s required for very large argument vectors
          while allowing the first malloc() to be a relatively small
          allocation for up to 126 matching file-name arguments.

util.c:
        * This is a new file for the integrated shell utilities.

        * Added a new `-e' command-line option to fd2 to simplify
          redirecting all conventional output to the standard error
          as diagnostic output.

        * Integrated the external `fd2', `goto', and `if' shell
          utilities as special built-in commands to improve shell
          performance.  Also, added `echo' as a special built-in
          command.  Osh executes each of these built-ins in a subshell.
          Consequently, the I/O for each can be redirected as before,
          and the argument list for each can be the result of a call to
          glob() as before.

-Osh is a re-implementation of the old and obsolete shell version,

+Osh is an enhanced, backward-compatible port of the original sh(1)
