Ah, this is an interesting ... we supported afm before we had otf
support and this is the reason why ligatures are enabled by default
(after all, they are in regular tex fonts). There is no reason to do
that now, so I'll change that default behaviour.

(maybe some day I'll provide node mode support for afm as well, but the
code originates from the early days so then I need to rewrite a couple
of things)
