[lucida] PDF font embedding for PDF/A, problem using Type 1 with accented characters

[Karl Berry]

    The lucida afm shows that the accented chars in this font are
    composites: the egrave is actually e + grave:

Thanh made the fix in pdftex (pdftex r902, TL r65870).
(Case CS_SEAC in writet1.c; it's the seac operator in Type 1 that's involved.)
Luigi is looking into propagating it to luatex. --thanks, karl.
