[tex-k] E193, E543ff: programs aren't copied around verbatim

Page E193, line 7 says:

    ...  (a copy of the program for `0' in romand comes here)
penlabels(1,2,3,4); endchar;

But if you consult the official MF sources, you'll find in itald.mf


where romand.mf says

    x2r=hround max(.7u,1.45u-.5curve);

So the skeleton of the italic "0" isn't quite the same as the roman "0",
despite what page E24, line 4 says.

Pages E543ff may have the same problem: compared with greekl.mf, the
skeletons of the Greek letters in tsetsl.mf have actually been optimized
for the extended-ASCII typewriter font.
