Subject: builtin-diff: fix comparison between two blobs.
X-Git-Tag: v1.4.0-rc1~138
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=e4e23f3a1c7734cdad60ba1274487ee6e2198de3;p=git.git

builtin-diff: fix comparison between two blobs.

The code forgot that setup_revisions() leaves parsed object
names in reverse in the list.
