That may also true for several other modules; in which case, it might
be better to figure out how to build this into G_parser().

g.mremove is a shell script, which makes implementing shell
substitutions somewhat easier.

glibc has the glob() function, which is apparently specified by
POSIX.2, although I would be reluctant to just rely upon its existence
(e.g. it might not be present on all platforms, or it may require an
additional library).

Only the standard reason: once a module becomes "official", changing
its behaviour becomes problematic.
