Subject: rebase -m: only call "notes copy" when rewritten exists and is non-empty
X-Git-Tag: v1.7.8.5~3
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ad687b447a87efaf61c39075da2ef81b85715186;p=git.git

rebase -m: only call "notes copy" when rewritten exists and is non-empty

This prevents a shell error complaining rebase-merge/rewritten doesn't exist.
