allowed/disallowed reads more natural in my opinion. This is also the wording we went with in current Underscore. Other than that, I'm happy to merge this, but please keep in mind that your changes have relatively little effect:

• This is a copy of Underscore that is never shipped to users. It is only used in testing.
• Underscore proper is not updated by your changes, although it also does not need them anymore.
• This copy will likely disappear eventually in favor of a copy installed from NPM, or otherwise it will at least be updated to a more recent version of Underscore.
