Re: [PATCH 2/3] validate_headref: use skip_prefix for symref parsing

Jeff King [off-list ref] writes:

Since the previous commit guarantees that our symref buffer
is NUL-terminated, we can just use skip_prefix() and friends
to parse it. This is shorter and saves us having to deal
with magic numbers and keeping the "len" counter up to date.

Ah, I should have read the whole thing before starting to type a
response to 1/3 ;-)

Looks good.
