Improved the option syntax by eliminating the --inherit=DEPTH option and
adding individual options to the ". [OPTIONS] FILE" command itself.  This
lets the user directly specify if the file is a per-directory file or not
(using -p) and if the rules are inherited or not (using -i).  The user
also specifies how high up the scanning starts for per-dir files by
specifying a path on per-dir files (e.g. ". -p /start/.excl").  Added the
-E option which is an easy way to specify ". -pi /.rsync-excludes".
