[GRASS-dev] g.mlist: exclude parameter wish

[Huidae Cho]

Markus,

We could add the exclude option, but I'm not so sure if we really need it.
You can solve your problem by using a more specific wildcard if Paul's
trick doesn't work.

pat="gpcp_1dd_p1d_[0-9][0-9][0-9][0-9]_count"

It's a little lengthy, but it works.  Any better examples where we might
want the exclude option?
