Perhaps, the search could include title names as well - this would be the
extension to g.list. This makes sense as you usually know if you are
searching maps/groups/... or modules.

On the other hand, g.search could provide unified simple search interface
for searching/listing maps and modules - a simple "fulltext" search for
word. This would wrap more general g.list pattern search interface. There
is few other things we could search: Mapsets, Locations, and color tables.
But let's ignore this for now.

g.search.module aspect

g.module.search sounds good. In GUI the tree and search tab is called
Search modules, renamed from ambiguous Module search. Your original
g.search is shorter and since it will be used in the command line, we
should probably keep it short. So, at the end, I would keep g.search unless
somebody is against that.

Also, keep in mind that the XML may change at one point. See explanations

[GRASS-dev] wxgui_items.xml: outdated

Certainly, although not for me now.

I suggest to put it to trunk as soon as you are comfortable with the code
and basic features.
