As said in other thread: it's nothing to
do. Case-sensitivenes is TRT here, case-fold would lead
into never ending trouble because of
multiplied--factorizing--calculations.

Think someone want to partial-complete not just one

~/DIRECTORY/FILE.TXT

but ~/d/d/d/d/f

with maybe several hundred files starting with [dD] in
the directories. Emacs wouldn't return from that task.

Here I see a soure of never ending bug reports.

Better to tell: partial-completion-mode works
case-sensitive. (As is, fine!)
