I spoke to Rob Pike yesterday and mentioned that I thought
that free carets were the single stupidest thing in rc.
Don't use them.  Take them out of the code.  (Apparently
I always knew this.  There's a comment in the code where
this is implemented that uses the word `embarassing.')

BTW, the bug is on line 318 of /sys/src/cmd/rc/lex.c:

	if(t->type!=WORD) lastword=0;

I think that changing this to

	lastword=0;

fixes it (I don't have a plan 9 machine, so I can't test it.)
