+% @insertcopying.  Here we must play games with ^^M's.  On the one hand,
+% we need them to delimit commands such as `@end quotation', so they
+% must be active.  On the other hand, we certainly don't want every
+% end-of-line to be a \par, as would happen with the normal active
+% definition of ^^M.  On the third hand, two ^^M's in a row should still
+% generate a \par.
+% 
+% Our approach is to make ^^M insert a space and a penalty1 normally;
+% then it can also check if \lastpenalty=1.  If it does, then manually
+% do \par.
+% 
+% Seems pretty fragile, but for the limited use of getting the copying
+% text (which should be quite simple) inserted, we can hope it's ok.
