Good, I'm not going crazy! But my search skills are apparently
atrophying. :)

It looks like we just addressed the git-gc issue there. for-each-ref
uses the "rawref" interface, so it gets fed broken things and warns
about them.

I'm tempted to say that it should just silently ignore broken symrefs,
as they're kind-of a normal thing. But I also think Sebastian's patch to
squelch stderr during completion is quite reasonable, too.

:short is slow because it checks for ambiguity. So it has to walk the
dwim_ref() rules backwards, checking if each possibility is an existing
ref.

Whereas strip=2 is literally just skipping past the early bits of the
refname string.
