Yes.

That doesn't work (I displayed all characters and on bell [1] that
bell character is not given the on_add_lines() callback. I think
that's because this is no character that is written to the console but
catched by urxvt.

I have a working C patch (found in the internet and improved a bit),
but I'd like to have this with a Perl extension so that I don't need
to re-build my urxvt on all machines I work.


Thanks,
