But Erik asked for something like to undo the abbreviation. To the best
of my knowledge there is not (and there is even a todo list entry :h
todo and search for abbreviation).

Perhaps it would be enough to simply drop an undo point, before
expanding an abbreviation in insert mode? Something like this patch
perhaps?
