Edit Tree Conflicts: trimmed long paths

[oleg....@gmail.com]

In Edit Tree Conflicts dialog long paths (that do not fit the dialog) are trimmed at end. And there is no way to see full path: dialog is not "flexible", tooltip with the full path doesn't appear, no way to scroll the text somehow. This concerns both dialog message and text on buttons below, so sometimes it's impossible to make an informed decision.
