Ah, that is a pity.

I find the multi-line mode very useful for finding code problems that span multiple lines.

I'm sure there are other options that conflict, and the solution is to normally write out some kind of informative error

Anyhow, since I'm too busy working on LibreOffice right now to work up a patch for git, I'll stick to using
     find | xargs grep
:-)
