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.

Looks OK to me.

Thanks. Please add that to the commit message. More specifically, use
the first line above as the first line of the commit message, and add

(capitalize-dwim, upcase-dwim, downcase-dwim): New functions.

at the end.

I'm tempted to bind M-u, M-l, and M-c to those new commands.

WDYT?
