I am sorry for this misunderstanding - obviously, I was not clear enough
-( What I intended to say, was:

the bug with .../*.suffix (* removal) happened (or had effect) only in case
of ambiguous prefix (at least so my test results). I did not mean anything
else.

Now, that I have been working with this a bit more, the result of this patch
is somewhat unexpected. Now, the /a/b/c/d expands the prefix even if nothing
would match. Returning to my expamle - the bug with /u/i/s/*.h was, that
this does match, but the match failed (because of bug). And current
/u/i/s/*.c -> /usr/include/sys/*.c is a bit too much ...

Yes, with your great completers all works as expected - with above exeption.

May I suggest, that this change would be backed off? Probably, with
configuration option (but I fail to see, when it would be useful). If direct
completion of /a/b/c/d fails, this is the job for approximate/correcting
completion then.

To be more precise - the change makes prefix to be expanded even if nothing
matches. I did not intend it, and did not ask for it.

P.S. Sorry for turmoil this week. But when after every patch I get different
results after pressing TAB ... :-)
