ripgrep needs a short flag for multiline search. Which should it be? -m and -M are already taken, and I'm not going to re-purpose them. The long flag is --multiline. For other available flags (of which there are surprisingly few), see: https://github.com/BurntSushi/ripgrep/issues/176#issuecomment-410748391 …
That was my original intention. But after actually trying to use it, it was clear that I wanted a short flag pretty badly. It's one of those things you might not use at first, and then you go back to your command and tweak it. Having a short flag for that is nice.
