serializing HighLine::String to yaml produces strange results about highline

[JEG2]

Strange results in that you just want a normal String? I'm just making sure I understand.

Yes, that, and the serialization does not appear to be reversible (which is the bigger problem):

require 'highline'
require 'yaml'

hl = HighLine.new
x = hl.ask("foo: ")
puts x.to_yaml
p YAML.load(x.to_yaml)

Output:

foo: bar
--- !ruby/string:HighLine::String |-
  YmFy
"YmFy"

Yeah, we do need to fix this.

This is a problem with YAML/Psych in ruby 2.0.0-p0 which does not handle subclasses of String correctly e.g.

require 'yaml'

class X < String
end

x =X.new('foo')
p YAML.load(x.to_yaml)

Output

"Zm9v"

I couldn't reproduce the issue anymore. I think it was fixed in YAML. Added a test on 1c6a8fa to serve as guard against any future regression.

[JEG2]

Perfect.
