Hi,

Yes, fs= looks better than separator=.  If there are no objections to
breaking this backward compatibility, I'll change it again to fs=.

I agree with you that something needs to be done for grass7.  Ideally,
g.mlist/g.mremove should be removed by extending g.list/g.remove.
Probably, grass7 will require one more library by default that handles
regular expressions (e.g., POSIX regex, pcre).  More generally, we could
implement regex expansion into standard options (too much?).
