-Rsync will copy the directory at each encountered mount-point unless this
-option is repeated. Note, however, that the attributes of this mount-point
-directory are copied from those currently visible in the filesystem, not
-the inaccessible attributes of the underlying directory.
-
-This option does not affect the "collapsing" of symlinks that options such
-as bf(--copy-links) perform, irrespective of what filesystem the symlink's
-referent may be on.
+If rsync has been told to collapse symlinks (via bf(--copy-links) or
+bf(--copy-unsafe-links)), a symlink to a directory on another device is
+treated like a mount-point. Symlinks to non-directories are unaffected
+by this option.
