I wholeheartedly subscribe to your suggestion: fixing the error
handling so that it matches the documentation.
We have to be very careful about incompatible changes here. Unless it
is absolutely clear that the current behavior is a bug, unless it is
absolutely clear that nobody would try to rely on it, we must assume
there are dozens of existing parsers that do rely on it. We do not
dare break them, not by default.
Now, what we could do is add a command (perhaps `%errorfix') that says
to use the corrected error behavior. This way, existing parsers won't
change, but the improved behavior is available for new or updated
parsers.
