In RegExp, "*" matches _zero_ or more of the previous chars. What you 
want here is "(g+)" for one or more g's.  Kind of counter intuitive 
since for ls or dir, the "*" has a slightly different meaning, ie, "ls 
g*" will get all files starting with "g".  Not so in regexp.

Reg exp takes some getting used to.  I learned from Larry Wall's Perl 
book, that seems to be the best reference with examples, and more 
complete than the Rev Docs.
