Well, you can call it a bug, if you add kerns between a pair of
already kerned characters, probably fontinst should ignore the 2nd
kern pair. But that would add a run-time penalty to an already
painfully slow program. Best bet would be to post-process the fonts
in perl. This is already a good idea for some other fonts which
generate huge easily-compressed kern tables.
