update sticky: note that setting the sticky bit on files is still possible,

but has no effect. Retain description of sticky files, but note that it is
historical.

Add small description of how current system works. Improve description of
sticky directories. Remove references to ld(1).

Remove no longer relevant BUG.

much assistance and ok otto@ and tedu@
