Subject: git-p4: Add copy detection support
X-Git-Tag: v1.7.5-rc0~115^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=4fddb41bd77dd0f685d8f79c81d3d40128578fe1;p=git.git

git-p4: Add copy detection support

Add new config options:
    git-p4.detectCopies         - Enable copy detection.
    git-p4.detectCopiesHarder   - Find copies harder.
The detectCopies option should be set to a true/false value.
The detectCopiesHarder option should be set to true/false value.
P4Submit can now process diff-tree C status and integrate files accordingly.
