        src/bin/sh: option.list options.c sh.1

Log Message:
Add a -r (version) option to sh

This new -r (or +r) option is for command line use only.
When encountered, the shell simply prints its version info
(such as it has, which isn't much) and exits (immediately).

This allows "funny" uses like
        sh -version
the -v and -e options are standard, and processed as normal
(changing nothing, yet, except setting the option).  Then the
'r' option is seen, the version info is printed, and the shell
exits.  Any remaining "options" (there is no "-o n" option) are
ignored, as are any other args given to the shell.

The string printed (currently) is just "NetBSD shell:" followed
by the value of the NETBSD_SHELL variable (which has been established
already by the time options are processed).
