[GRASS5] [bug #2238] (grass) r.series: support for wildcards in input filenames

[Huddleston, John]

Hi Glynn,

The g.parser usage is <filename> [<argument> ...]  

For it to be changed the logic would be to loop through the arguments 
until a non-file name occurs.   Logic would have to be added to see if
any arguments remain.    If this is acceptable design, I can add the code.

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().

but not critical.

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.
