I can see two meanings for "the original locations" -- does it mean
the locations stated in the edited grep output, or does it mean the locations
that _were_ stated in the original grep output (before editing it)?

If it is the former, then can't you do this with C-u C-x ` ?
I just tried it and it worked.  C-u C-x ` reparses the error locations
in the buffer.

Actually editing the text in the Grep mode buffer is a nuisance, since
many self-inserting characters do unusual things.  But that is a
different issue.
