I just looked at the problem and I think it's not a bad fix.
The problem is that the default completion has changed (the text after
point is not considered any more) whereas partial-completion-mode hasn't
been changed accordingly (and some of its features clash with it).
Maybe a cleaner fix would be to add a variable, similar to
`completion-base-size' but which describes the number of chars at the end of
the buffer which are not part of completion: such a fix would require
changes in the default completion, but would make partial-completion-mode
work unchanged (i.e. it makes the new functionality more
backward-compatible). Not sure if it's worth the trouble.
So I guess the proposed patch is OK, but it would benefit from having
a larger comment explaining a bit of the problem. Should I install it?
