Quoted strings and integers/float/null/bool parsing

[kit-ty-kate]

ocaml-yaml 1.0.0 "adds supports" for float, null and bool values. However there is no internal distinctions between plain strings and quoted strings and this give wrong results. For example:

# Yaml.of_string "'null'";;
- : Yaml.value Yaml.res = Result.Ok `Null
# Yaml.of_string "'1'";;
- : Yaml.value Yaml.res = Result.Ok (`Float 1.)
# Yaml.of_string "'true'";;
- : Yaml.value Yaml.res = Result.Ok (`Bool true)

Those will of course return non-symmetric values when casted into strings using Yaml.to_string and will make something like "null" == null or 'true' == true.

Thanks, patches for this welcome. In particular, what does the spec say about how this should behave? Is the interaction between the implicit quoting well defined?
