Re: [PATCH v2 00/12] coverity: avoid dereferencing NULL

This is a continuation of the effort I started in the patch series that
became js/coverity-fixes. This next batch adds guards to avoid dereferencing
NULL pointers and accessing NULL file descriptors.

Changes since v1:

 * Calling remote_tracking() no longer returns -1 when remote is NULL, but
   instead BUG()s out.
 * bisect_successful() returns with BISECT_FAILED instead of the -1 that
   only worked by happenstance.
 * The commit "revision: avoid dereferencing NULL in add_parents_only()" now
   comes with a regression test.
 * The commit "bisect: ensure non-NULL head before using it" no longer
   claims that the fixed bug can be triggered with the current code base.
 * The missing shallow commit's OID is no longer computed twice.
 * A follow-up commit was folded into this patch series that lets
   write_one_shallow() avoid the rolling buffers of oid_to_hex(), as
   suggested by Junio. It technically does not fit the goal of this patch
   series (fixing issues pointed out by Coverity), but was asked for
   explicitly.

I found everything including the new patch good.  Unless others find
more issues in this round in a few days, let's mark the topic for
'next'.

Thanks.
