Okay, good :).

Would it? One would be in 'directories' and one would be in
'path-directories', same as now except the first one is in
local-directories. What I meant was path-directories would stay, but
local-directories would be folded into directories, since they never
appear at the same time anyway. I suppose the issue is academic since
we can't break existing configurations though.

Do you mean in front of the path-directories? cd goes to local
directories first, and then cdpath.
