[PATCH v2 0/2] Check for lock failures early

Callers outside of refs.c use either lock_ref_sha1() or lock_any_ref_for_update() to lock a ref during an update.

Two of these places we do not immediately check the lock for failure making reading the code harder.

One place we do some unrelated string manipulation fucntions before we check for failure and the other place we rely on that write_ref_sha1() will check the lock for failure and return an error.

These two patches updates these two places so that we immediately check the lock for failure and act on it. It does not change any functionality or logic but makes the code easier to read by being more consistent.

Version 2:
* Simplify the return on error case in sequencer.c.

Ronnie Sahlberg (2):
  sequencer.c: check for lock failure and bail early in fast_forward_to
  commit.c: check for lock error and return early
