Subject: git-p4: avoid syncing duplicate changes
X-Git-Tag: v1.6.2-rc2~15
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=b4b0ba06f8748348039d56ffa5890590dd9776ee;p=git.git

git-p4: avoid syncing duplicate changes

When a particular changeset affects multiple depot paths, it
will appear multiple times in the output of "p4 changes".
Filter out the duplicates to avoid the extra empty commits that
this otherwise would create.
