Subject: git-gui: Refactor the revert (aka checkout-index) implementation.
X-Git-Tag: gitgui-0.6.0~117
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=7d40edfa06adf7f31f787bb6379c1eb454242c19;p=git.git

git-gui: Refactor the revert (aka checkout-index) implementation.

We can revert any file which has a valid stage 0 (is not unmerged)
and which is has a working directory status of M or D.  This vastly
simplifies our pattern matching on file status when building up the
list of files to perform a checkout-index against.
