The original zap-to-char doesn't provide much. The enhancement - our
zop-to-char doesn't improve the situation either.
The same goes for zap-up-to-char and zop-up-to-char. So asking me to
come up with one is... sigh, anyway here you go.

Fixed. Sorryyyyyyyy.

I did and... hmm looks like it's time to visit the ophthalmologist again.

I reworked the patch and I'm resending it in the attachment.

Cheers
