ligatures in lilypond can currently be engraved only in one shape,
although some combinations could be written (and were written, as you've noted)
in several ways.
see ligature-description.txt in
http://lists.gnu.org/archive/html/lilypond-devel/2005-02/msg00198.html
on how to write (read) ligatures.
