[PATCH v3 1/2] revision: document get_reference()
In particular, document the behavior when the object is corrupt. The
existing behavior when parse_object() encounters a hash mismatch has
been there since cc243c3ceb ("show: --ignore-missing", 2011-05-19), and
the existing behavior when the code disagrees on whether an object is a
commit has been there since ec0c5798ee ("revision: use commit graph in
get_reference()", 2018-12-28).
