Ah, as it turns out, pic is emitting an .nf request.  I suspect when
used within a macro this is not reset properly.  A quick hack is below,
but this is surely incorrect as .fi may not have been on before the
macro is called (I checked, it causes lines to be wrapped after a pic
even if .nf was set prior).  The correct fix would seem to be looking
into fixing something other than the symptom, but this (or just putting
.fi in the macro after .PE) would seem indicated ;^)

Cheers,
