Adding

#% multiple : yes

to the option def'n will "allow" multiple input names (for shell scripts
this only really changes the help text I think)

For patterns, use "g.mlist sep=, pat=$GIS_OPT_input" to parse the string.

I don't know if using muliple+patterns will work on the same input line.
Maybe some g.mlist enhancement is required for that.
