Problems with the listings package

[Karl Berry]

Hi Jobst,

    The question is, whether I should fix the error after such a long time

I think it's good to fix errors, yes.

    and how can I assure compatibility with the current user
    documents/package documentation?

Of course it's your choice, but my gut reaction is that isn't
significant enough to warrant a new package option to preserve the old
behavior. Instead, you could make it possible for people to use the
LaTeX rollback feature to get the old behavior if they really want
it. I can't say what, exactly, but there is doc and examples around on
the rollback stuff.

My further hunch is that most users would be happy to have the options
work as originally intended/documented and not be worried about the
change in output. But who knows.

Maybe others here have better ideas ... --thanks, karl.
