Here's a changed patch. The first line is the first line of the changelog
entry without "simple.el"; it doesn't fit.

I'm in favor of changing M-u, M-l, and M-c to the new commands; I think
it's much improved behavior. The only time a user would have to do more
work to perform a capitalization action is if they've selected a region,
but want to act only on the next word. I would bet that's rare, and even
so, the user only has to press C-g before the capitalization. So if we're
ok changing default commands, I think changing M-u, M-l, and M-c is a win.
