What happened to _path_files?

["Andrej Borsenkow" <Andrej.Borsenkow@xxxxxxxxxxxxxx>]

bor@itsrm2:~/tmp%> zsh -f
itsrm2% autoload compinit ; compinit -D
itsrm2% cp _man /t/s/z/C/U<TAB>

beeps

I have /tools/src/zsh-* and /tools/share/zsh/* . I never get any menu or list.
The same settings as before (here is zsh -f just to demonstrate problem).

This is zsh-3.1.6-pws-6 with 8056. Looks, like ambiguous matches do not work any
more. I can complete, if match is unambiguous (but not, if it is with
metachars):

bor@itsrm2:~/tmp%> cp _man /a/p/u/z/p/<TAB>
bor@itsrm2:~/tmp%> cp _man /archive/pub/unix/zsh/patches/3.1.6-pws-6/

but

bor@itsrm2:~/tmp%> cp _man /a/p/u/z*/p/<TAB>

just beeps.

Again, all this worked before pws-6 (I skipped several pws-XX).
