ref_cmp_full_short(full_name, short_name) expands short_name according
to the rules documented in git-rev-parse and compares the expanded
name with full_name. It reports a match by returning 0.
This function makes the rules for resolving refs to sha1s available
for string comparison. Before this change, the rules were buried in
get_sha1*() and dwim_ref().
ref_cmp_full_short() will be used for matching refspecs in git-send-pack.
