[PLUG] Configuring fc-cache search path

[Rich Shepard]

   The fc-cache man page explains that the tool searches all system path
directories for fonts, but not where this is controlled. Here I have removed
the Speedo and cyrillic subdirectories under /usr/share/fonts/ yet they
still appear in the searh list (with no fonts found).

   While harmless I'm curious to learn where this path information is stored
so I can remove the two non-existant directories.
