I don't want to constrain backporting.

OK, had a look through the full log....
There are no other commits introducing the bug (renaming and
merging files without changing functions doesn't count), except for the
initial import into git. So I'll add that one, too.

The first Fixes commit definitely introduced a new buggy user.
The second Fixes commit is debatable, as it copied the bug for a new
function from two functions that were removed in the process.
