IIRC, it happens when HEAD points to a broken ref. So something like:
git init
echo broken >.git/refs/heads/master
would cause resolving HEAD to return NULL.
That worked and I see "(unknown)".
This is a bit of a nit, but is there a value we'd like
to see there, such as "(unknown)" or "(broken)" or "(missing)"
in that case? (And make it clear that this is a different
case from "(detached)".)
I'm thinking it would be nicer to always have a field
there for parsing.
My gut feeling is to err on the side of being vague, like "unknown".
This is something that _shouldn't_ ever happen, and if it does, it could
be a broken on-disk ref, a transient syscall error, or some other
weirdness. I don't think we need to get too specific in this context
(we'll likely have said something else useful on stderr already, I
think).
