Revision: 5901
Log message:
Simplified the Shell.chdir function a little.
Introduced the concept of a "mount point," to
separate the choice of edit object from the
chdir function.
This doesn't change whether we should use real
objects for edit objects. However, it does suggest
that edit objects should not handle ".." paths; that
choice is performed by the mount handler.
