        src/bin/sh: input.c

Log Message:
Another fix from FreeBSD.   I'm not sure how to trigger the problem
fixed (there might be no way) - but it "feels right"!

When popping an (exhausted) input string off the input stack, allow
for the possibility that the previous string might also just happened
to have run out of steam as well, so keep poppin' along until we
run out of pop, or find something to consume.
