Huh? Contrary to skip-chars-forward, forward-line returns the number of
lines remaining, not the "decrease in the number of lines remaining".
I.e. (zerop (forward-line 1)) is often used to check that forward-line has
indeed moved.
I agree with Martin that it would be better to not return 0 when it has moved
but hasn't managed to move to a different line.
Ok, I agree.
Would someone like to change this?
It is important to check that the various callers that look
at the return value will still work. But I tend to think they
mostly will, because this change would increase the consistency
of the return value.
