It does not fix the issue about loosing fonts I have reported,
I still see the same problem.

Although it does fix JimC's issue that path names are not
stored in the per-directory cache files, it creates the
problem that fc-list cannot list the path to the fonts anymore.

For example, if I have two copies of tahoma.ttf and tahomabd.ttf
in ~/.fonts and in /usr/X11R6/lib/X11/fonts/truetype:

mfabian at magellan:~/.fonts$ ll tahoma*
-rw-r--r--  1 mfabian suse 379588  8月  6  2004 tahoma.ttf
-rw-r--r--  1 mfabian suse 352020  8月  6  2004 tahomabd.ttf
mfabian at magellan:~/.fonts$ ll /usr/X11R6/lib/X11/fonts/truetype/tahoma*
-rw-r--r--  1 root root 257636  9月 22 06:57 /usr/X11R6/lib/X11/fonts/truetype/tahoma.ttf
-rw-r--r--  1 root root 252384  9月 22 06:57 /usr/X11R6/lib/X11/fonts/truetype/tahomabd.ttf
mfabian at magellan:~/.fonts$

Then fc-list cannot tell me anymore where in my system the "Tahoma"
fonts are:

mfabian at magellan:~/.fonts$ fc-list : family file | grep -i tahoma
tahoma.ttf: Tahoma
tahomabd.ttf: Tahoma
mfabian at magellan:~/.fonts$

Even if only the local file name is stored in the per-directory
cache-files, fc-list should be able to list the full path names,
shouldn't it?  While reading the cache files, fontconfig knows from
what directory the cache file has been read.
