sorry, scratch that. It does work.

Thunderbird turned $arg _hat_ 0 into $arg _superscript_ 0, which became
$arg0 when I copy/pasted. And I didn't catch it. Again, apologies.

I think this is the intuitive behavior, prefer branch over tag. though I
think a warning or refusal to switch would be better (but more
complicated, and I don't know how to do it).

A quick run through of some other porcelain commands shows they prefer tag:
git log
git show
git diff
