Always display prefix, even if unambiguous?

Always display prefix, even if unambiguous?

Greetings! I don't know if this counts as a bug or I've overlooked 
something, but I can't figure out how to make zsh's compsys to always 
display the full path when completing filenames, for example:

ls /usr/s/l<TAB> generates:
*files:**
**sbin/ldattach* sbin/lpadmin*             sbin/lshw* 
share/libbluray/          share/liblangtag/ share/llvm/               
src/linux@ **
**sbin/locale-gen* sbin/lpc*                 sbin/lspci* 
share/libexttextcat/      share/libquvi-scripts/ 
share/locale/             src/linux-3.17.7-gentoo/**
**sbin/logoutd* sbin/lpinfo*              share/lcdf-typetools/ 
share/libidn/             share/librarian/ share/log4j/ **
**sbin/logrotate* sbin/lpmove*              share/lftp/ 
share/libjpeg-turbo/      share/libtool/            share/lshw/ *

which is fine. If I add the file-pattern style:
zstyle ':completion:*' file-patterns '*(-^/):files:file 
*(-/):directories:directory' to separate files from dirs, I get:
*file:**
**ldattach*         locale-gen* logoutd*          logrotate*        
lpadmin* lpc*              lpinfo*           lpmove* lshw*             
lspci* **
**
**directory:**
**share/lcdf-typetools/ share/libexttextcat/      share/liblangtag/ 
share/libtool/            share/log4j/ src/linux-3.17.7-gentoo/ **
**share/lftp/ share/libidn/             share/libquvi-scripts/ 
share/llvm/ share/lshw/ **
**share/libbluray/ share/libjpeg-turbo/      share/librarian/ 
share/locale/             src/linux@ *

i.e. it does not list the directory of the files, because they are all 
in sbin and zsh seems to treat the dirs and files completion separately 
now. If I complete something like
ls /etc//a<TAB> I get:*
**file:**
**acpi/ati-powermode.sh* ati/amdpcsdb.default        conf.d/acpid 
conf.d/atieventsd           init.d/atd* mail/aliases.db             
pam.d/atd **
**at/at.deny ati/authatieventsd.sh*      conf.d/alsasound 
init.d/acpid*               init.d/atieventsd* 
modprobe.d/aliases.conf     security/access.conf **
**ati/amdpcsdb at-spi2/accessibility.conf  conf.d/atd 
init.d/alsasound*           mail/aliases modprobe.d/alsa.conf **
**
**directory:**
**acpi/actions/ lvm/archive/ ssl/apache2/ 
terminfo/a/                            xdg/autostart/*

the full path (relative to the unambiguous prefix /etc) is listed for 
both files and dirs, since the paths are ambiguous in both cases.

I hope I made myself clear. How can I "fix this"?

You haven't made yourself entirely clear because there must be some
zstyle values or other settings that get you to the situation you have
so far.  For example, I can't get anything even close to your example
output without at least "setopt globcomplete".

However, I *think* the answer to your question is "you can't."  The
_path_files completion function unconditionally passes the -p (hide
prefix) option to "compadd" with the longest unambiguous directory
path of every file name that it finds.  

I thought perhaps the "fake" style could be caused to create a false
ambiguity that would get you what you wanted, but I haven't managed
to formulate a working example.

Sorry about this, I'm attaching the relevant (and maybe some irrelevant) 
parts of my .zshrc
I changed from using file-patterns to simply list-dirs-first, which 
seems to have the same effect (without allowing me to manually specify 
tags and desciptions). In any case, if anyone has an idea for a 
workaround, I'd love to hear it
