Let dir locals for more specific modes override those from less
The list of dir local variables to apply is now sorted by the number
of parent modes of the mode used as the key in the association list.
That way when the variables are applied in order the variables from
more specific modes will override those from less specific modes.
If there are directory entries in the list then they are sorted in
order of name length. The list of modes for that dir is then
recursively sorted with the same mechanism. That way variables tied
to a particular subdirectory override those in in a parent directory.
Previously the behaviour didn’t seem to be well defined anyway and was
