Re: [PATCH (GIT-GUI)] git-gui: Reenable staging unmerged files by clicking the icon.

> This restores functionality of the file icon for unmerged files.
> Safety is enforced by loading the diff and checking for lines
> that look like conflict markers. If such lines are found, or
> the conflict involves deletion and/or symlinks, a confirmation
> dialog is presented. Otherwise, the icon immediately stages the
> working copy version of the file.
