Subject: lock_ref_sha1_basic(): remember the original name of a ref when resolving it
X-Git-Tag: v1.5.0-rc4~49^2~11
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=1655707c9ec56847945854f8645ed64f74159e99;p=git.git

lock_ref_sha1_basic(): remember the original name of a ref when resolving it

A ref might be pointing to another ref but only the name of the last ref
is remembered.  Let's remember about the first name as well.
