Compacted directory list

If there are two directories in the list named, for example, /usr and /usr/X11R6/lib/X11/fonts/Type1, the former is considered to be contained in the latter and only the longer name appears in the list.

If you then choose /usr/X11R6/lib/X11/fonts/Type1 from the list, CLEX splits it into components like this:

/usr/X11R6/lib/X11/fonts/Type1
/usr/X11R6/lib/X11/fonts
/usr/X11R6/lib/X11
/usr/X11R6/lib
/usr/X11R6
/usr
/

and the /usr directory reappears this way.
