Type1 smallcaps fonts used to do that, not sure why, but probably
because some applications were doing ligature replacement incrementally
and I think it propagated to some (early?) Adobe OpenType fonts. Also,
some fonts seem to use such smallcap ligatures to fix bad interaction
between ‘liga’ and ‘smcp’, but that is the wrong way to fix it.
