If a font has the same kern pairs for M and N (which, let's face it is
pretty likely) then fontinst will just generate the duplicate ligtable
for both, rather than combine them into one ligtable.  This makes a big
difference for some commercial type 1 fonts, which seem to have kern
entries for just about every pair of characters.  It's especially
noticable in small caps fonts.
