I don't have a clear answer to your question, below, but a couple of
points that *MUST* be made: You are not posting to a forum with
*either* the "Ruby on Rails 'forum'" or the "Ruby 'forum'". You are
posting to a mailing list gateway. You are correct that this probably
belongs on ruby-talk (the mailing list to which your post has been
gatewayed) and comp.lang.ruby (the newsgroup to which the mailing list
is bidirectionally gatewayed). But it's not a forum.

It does appear to be a documentation bug or a code bug that was
introduced; someone else will have to verify that.

I didn't even know about this ;)

I suspect that it's not filled because it's not how the documentation
is dealt with in Ruby.

Lastly, your example:

   p URI.escape("@?@!", Regexp.new("[!?]"))
   # => "@%3F@%21"

Can be rewritten as:

  p URI.escape("@?@!", /[!?]/)

You don't need Regexp.new.
