+ read_fonts_conf_indeed() -- Scan paths included from fontconfig

The first four are
+
· the path to the file
· the expanded $HOME
· the expanded $XDG_CONFIG_HOME
· the expanded $XDG_DATA_HOME
+
+ determining the path to be checked. Another three arguments are
+ tables that represent the state of the current job as lists of
+ strings; these are always returned. Finally a reference to the
+ find_files function is passed.
