Hmm... i've just checked, and found that when those lines are
uncommented, fontinst generated duplicated kernings, e.g.:
(LABEL D 27) (COMMENT ff)
(LIG D 105 D 30) (COMMENT i ffi)
(LIG D 108 D 31) (COMMENT l ffl)
(KRN D 39 R 0.7699) (COMMENT quoteright)
(KRN D 63 R 0.7699) (COMMENT question)
(KRN D 33 R 0.7699) (COMMENT exclam)
(KRN D 41 R 0.7699) (COMMENT parenright)
(KRN D 93 R 0.7699) (COMMENT bracketright)
(KRN D 39 R 0.7699) (COMMENT quoteright)
(KRN D 63 R 0.7699) (COMMENT question)
(KRN D 33 R 0.7699) (COMMENT exclam)
(KRN D 41 R 0.7699) (COMMENT parenright)
(KRN D 93 R 0.7699) (COMMENT bracketright)
(STOP)
there are 10 kern pairs, of which the last 5 repeat the forst 5. This
looks like a bug in fontinst... I'm mailing a Cc: to the fontinst
list.
Description of a bug: if one uncomments some commented kerning stuff
in aelatin.mtx from the ae fonts package (e.g. shown above), then
fontinst generates duplicated kernings. Please, help to fins the
reason/correct this problem.
Best regards, -- Vladimir.
