Subject: combine-diff: Honour --full-index.
X-Git-Tag: v1.2.4~5
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=b9003c06a89a6d78255bb837c921ca03ee27fae6;p=git.git

combine-diff: Honour --full-index.

For some reason, combined diffs don't honour the --full-index flag when
emitting patches.  Fix this.
