No, you're not -- I agree that this change in behaviour makes sense.  I
simply hadn't anticipated this effect when I first did the work.

So should the commit message simply say "This changes the default behavior of
'git push' ..."?  Or are you suggesting the message needn't mention it at all?

Thanks, I understand you now.

I feel it's rather surprising that git defaults to "origin".  I think the
docs should explain that git in fact ignores whatever remotes are actually
configured in the repository, that git only looks in specific places for a
remote name.  That's what I was trying to convey with the "even if" clause.

I'll try to rephrase.
