If you have a file named "åäö.txt" and you have auto-completed it, deleting
a character simply means pressing backspace. Earlier, when deleting, say,
the "ä", it was converted to an "a", so you had to press backspace twice to
delete a single character.

I will be away for the weekend, so if you have write access, feel free to
commit it yourself. Otherwise, I can do it at the beginning of next week.
Personally, I think this should go into the emacs-25 branch but we will
have to get that approved from John or Eli.
