If someone wants to add a more user-friendly dialog for searching text
(or perhaps reuse a dialog provided by the GUI toolkits), I think it
will be welcome.  It is not a simple job, though, because the dialog
should allow access to most of the advanced features of Grep.

FWIW, I don't think rgrep is significantly more user-friendly, so IMO
it is not the model on which to base a better UI.
