Barbara, the problem with Winnrpennicksxt
was due to the overfull box making the badness so high that the
line-breaking routine couldn't distinguish between 1000000000005 and
1000000000000. I changed it so that it will take a more probable turn
in such cases next time. Also, your definition of \pfill should not be

\def\pfill{\hskip .5em plus 5000pt\penalty 500\null\!
	\penalty 1000\hskip .5em plus 5000pt\!}

it should be

\def\pfill{\penalty500\hskip .5em plus 5000pt\null\!
	\penalty 1000\hskip .5em plus 5000pt\!}

although the way you have it isn't too bad.
