`g' in that window, then `M-p' should show you the last `grep' command, with
its regexp. Does that help?

Ah, so this is not about `M-x grep'. I guess it's about `grep-find'.
Still, repeating the command and using `M-p' should show you the previous
command used, including its regexp.

The regexp you typed was not seen as such by Emacs. All that was seen was
the entire input command, including that regexp. To extract the regexp I
think you would need to add code that matches that input against the template
`grep-find-command', which has the hole into which you inserted the regexp.
Maybe someone else can help more; sorry.
