Yes, I agree \msg_space: doesn't need to exist when \c_space_tl does.

Oh yes, `\ \ \ \ ` would be pretty good. (My brain thought they'd be concatenated for some reason and I didn't try it. Distracted by other work, I suppose.)

I'm probably happy to leave things as they are for now. In fact, any sort of "indent" function would be better if it respected the line-wrapping routine and that's more work than it's worth right now. I'll table this thought in the Github wiki.
