I wish they would make long option names for everything, including -C and -M. (Perhaps I should contribute that..)

I use short options interactively on the command line, but in scripts and when communicating with other people, I prefer longer options because they are self-documenting and can catch most typos. (For a long option, typos are more likely to result in an invalid option, and thus an error message. For one-letter options, a typo could result in anything..)

FWIW, -C has precedents: `make` and `tar` have the same option with the same meaning.

Yes, sticking to precedent is a good idea in general, too. But that's independent of long options.
