addremove: correctly handle intermediate symlinks This fixes problems mentioned in issue660 comments (unrelated to original issue) where directory was renamed, and symlink was added instead. In such situation addremove wasn't able to correctly detect that old files no longer here, but tried to add symlink (and failed due collision with old files).

Basic install:

 $ make            # see install targets
 $ make install    # do a system-wide install
 $ hg debuginstall # sanity-check setup
 $ hg              # see help
