[reportlab-users] How are split, wrap, wrapOn supposed to work?

[Andy Robinson]

Henning, I'm sorry about the lack of reply.  We have been tied up with
a very complex series of software releases this week.  And to be
honest I need some time to remember how this code works, it's been
about 10 years since I touched it :-(

My first impression is this:
> What should a flowable do if wrap is called with availWidth <= 0?
We never thought of it, but I guess raise a LayoutException?

see above.

We're working on core stuff next week - I hope.   We will try to pull
your code down and look then.
