I was loosely aware of that but never got it into my fingers. Instead I
was relying on that dwim behavior of diff-mode. But trying the prefix
variant out, it seems to be a solid way of "un-applying" a hunk.

Might not be worth the trouble to try and fix this problem if it is
complicated. There is a solid way to do what I want (which is maybe the
proper way), and my complaint about this is the only one I have seen. A
wont-fix is fine with me.
