Mapster32: "Set starting position" can't be UNDOne
Probaly never worked. Oldest tested version: svn2492 (3cc0d523). "Set starting position" (Scroll Lock) is counted as edit, and Mapster32 claims "Undo: restored revision xyz" when pressing CTRL-Z, but doesn't do anything. No big deal for actual mappers, I suppose, but a minor annoyance to me when reviewing maphacks.
