Hmmm... I don't think I see that. Both completion-in-region-mode and
the condition at that place haven't changed in a while. The addition
of completion-use-base-affixes part is new, but since it's via 'and',
it cannot have changed what the code before did, only cause it to do
that in fewer cases. What am I missing?

This is all undecipherable for me, sorry. What is that "new feature",
and how is it fixed here? And how is bug#61479 relevant?
