I quote your suggestion here:

I didn't understand your suggestion fully initially, sorry.  I think
you're suggesting that the user should pick a "window" between two
places in the file.  Then the user can only edit the file between those
two places.  That `grep' is producing the list of places is not as
important as the idea of having those places.

Yes, I believe so.  I'll try to implement the items I listed and perhaps
someone can use them productively, to implement the UI you suggested or
something else.

Thanks for your help and time.
