[feature] 4-way diff / multiway diff #2962
Description
WinMerge supports up to 3 files diffed. But with larger monitors, we have the space to diff more files, and (very unfortunately) we sometimes have to merge four or more conflicting variants of a source file. Yes it's horrible but that's life.
Four-way / multi-way / N-way diff would be extremely helpful. Vim can do it but it's a pain.
