% Following change commented out 940614 for the following imperfectly
% understood reason.  When the partopsep is NOT set here, it is zero
% at the beginning of a run (even though defined to be 3 +2 -2 in
% art10.sty).  When it is set here, it is nonzero, and breaks the
% footnotes on the first page of amsart.sty.

% Extra vertical space, in addition to 
% \parskip and \topsep, added when user
% leaves blank line before environment.
% (Changed from 3 +2 -2)
