FWIW I picked this up from the perl list where both are used depending
on context. I.e. DW[IY]M depending on if the sentence is one where you'd
describe things from a first or second-person perspective "I implemented
this to DWIM, and it'll DWYM if you invoke it as...". Also
"dwimerry"[1].

Yeah maybe this is going too far. I don't think so, but happy to me
challenged on that point :)

I don't think so because the only reason I've ever needed this is
because I deleted some branch accidentally and am using a push from
"remotes/*" to bring it back. I.e. I'll always want branch-for-branch,
not to push that as a tag.

Of course it isn't actually a "branch", but just a commit object
(depending on the refspec configuration), so we can't quite make that
hard assumption.

But I figured screwing with how refs/remotes/* works by manually adding
new refspecs is such an advanced feature that the people doing it are
probably all here on-list, and would be the sort of users advanced
enough to either know the semantics or try this with -n.

Whereas the vast majority of users won't ever screw with it, and if they
ever push from remotes/* to another remote almost definitely want a new
branch under the new name.
