Yes, but I don't see how highlighting what exactly matched is of any
help in that case.  Especially with the weirdo matches some aggressive
completion styles produce.  I care about the candidates and about how
to narrow the list, not about how and why the completion picked up
these particular candidates.

That's what the "first difference" highlighting solves.

Sorry, I'm unconvinced.  I cannot think of a situation where such
highlighting would help me.
