hey william !

thank you very much for your help !!

i got it working, sort of. a few problems remain, surely due to the use
in bibtex, but that's okay / i hope to be able to fix them.

but besides -- i tried many ways of determining the remaining space. why
do things like \newlength{\temp} \settowidth{\temp}{\fill} not work ?

i'd still have some other use for the wanted macro (\remainingspace that
is).

have you, or anybody else got any ideas for that ?
