Subject:      the algorithm for nfss (math)
Status: R


the file that finally made it to the server after all will not run
when you have an \halign inside math, eg array environment. this is
because the \aftergroups can't be stopped (as it was done in the old
algorithm) by using an extra group.

at the moment i don't see a clean way to solve this short of turning
$ into an active character (always). that would in fact solve more than
one problem and would make the code in this case much simpler.

if anybody has some good thoughts i would be glad to learn  about them.
but i won't look into this in the next days but rather do the finishing
touches on latex2e. if we get something clean it can still be added later
on.

cheers
frank
