hidden composites


there exist some fonts (like Monotype baskerville or Lino didot) where
the AFM declares true chars that are indeed composites built in the
PFA by  a seac construct. These may fool some partial font downloading
software (downloading the PFA definition of egrave in mbvr8r willnot
download the two outlines needed to print this char). An example being
the current pdftex.

As these PS fonts are usually used through fontinst's VFs,  I think it
would be more interesting to redeclare these chars as composites in
the AFM, and do the composition inside the VF, which would solve this
particular problem. 

Does anybody know how to add the composite section of the AFM when the
only available info is the seac construct in the PFA?

Any different reaction?
