Subject: UseFold in YAML

Hi,

while we're at it ..

I try to make YAML fold newlines.  Sometimes it does, sometimes it
doesn't.  Does anyone has an idea of what's happening here?  Or is
this just the way YAML works?  Thanks.

require 'yaml'

text =
"Just got my (dead-tree, printed-on-paper, " +
"I don't know if there's a web " +
"version) copy of Linux Magazine for September, 2002." +
"There's an article by " +
"Dave Thomas about building networked applications in Ruby." +
"Props to Dave!" # i.e., no newlines

hash = { 'key' => text }

puts text.to_yaml( :UseFold => true,
                   :BestWidth => 15 )

produces:
--- >-

r, I don't know
