HighLine freezes when using wrap_at and page_at

Hi all,

I'm experimenting a small problem when trying to use HighLine with
wrap_at/page_at options... The script below leads to a deadlock under MacOS
with all ruby installations I have (rvm)

<pre>
require 'rubygems'
require 'highline'
h = HighLine.new
h.wrap_at = 10
h.say "a"*100
</pre>

Something I don't understand ??

thanks,
B

Nope, it looks like you found a bug. I believe I have it fixed on =
Github now:

Can you confirm that code works for you?

Thanks.

Works perfectly now

P.S. Don't know it's a bug, but with page_at set to :auto, two lines are
hidden on each page (probably due to the "\n-- press enter/return to
continue or q to stop -- q" message). Don't know if it's clear, ... you can
try the following:

<pre>
require 'rubygems'
require 'highline'
h = HighLine.new
h.page_at = :auto
h.say((1..1000).collect{|i| i.to_s}.join("\n"))
</pre>

On a terminal 80x24, the first page starts shows 3 to 24, the second page 27
to 48, and so on.

Anyway, using "h.page_at = h.output_rows-2" works fine...

Thanks a lot,

Looks like a bug to me, yep.
