> You can avoid the whole patch by `ln -s /usr/bin/rg fake-bin/grep` and put it into `$PATH`

@sgn I think the patch is needed anyway because sometimes `grep` & `rg` have slightly different options: `-U` in `rg` vs  `-z` in `grep` for multiline mode. Though I can make the patch a lot smaller if I employ your approach. Should I do that?
**UPD** hmm, I can just use `sed` probably
