This is not what wgrep.el does, so this bug report is not about that.

This is the issue we are discussing here, as that is what wgrep does.
It works well in practice, analogous to how wdired works but it edits
multiple files.  You enter wgrep-mode from grep-mode to make your edits
with `C-x C-q', edit the text of the buffer and then type `C-x C-s' to
save your changes to the relevant files.

This is very similar to wdired.
