I've already made a little pull request here https://github.com/ruby/ruby/pull/691.

The diff is here: https://github.com/ruby/ruby/pull/691.diff

But to make the real changes clear is it better to ignore white-space (as there are many indentation changes).

Changes ignoring white-space: https://github.com/ruby/ruby/pull/691/files?w=1

Rather I think it a bug of RDoc.

[eloyesp (Eloy Esp)]

I don't think that it is only a bug in RDoc.

There are at least 3 ways to define class methods in ruby, and I think that all are acceptable, but define two class methods in different ways in the standard library it's not a good example, nor a good practice and does not help in readability.

Ok, there is a lacking feature in RDoc, but I don't think that keeping it that way is the way to go.

[nobu (Nobuyoshi Nakada)]

It's valid code, at least.
Whether you consider it a good example or not is another story.

This may be a bug in RDoc, but we can fix it without redefining the methods by using the document method directive:

See http://docs.seattlerb.org/rdoc/RDoc/Parser/Ruby.html#class-RDoc::Parser::Ruby-label-Metaprogrammed+Methods

Could you send a patch for this instead?

[eloyesp (Eloy Esp)]

I've tried to fix it only touching documentation, and it seems to be
impossible, rdoc does not understand the class << self syntax (I
understand rdoc in this point, ruby is not easy to parse). I've added an
issue in Rdoc for it ( https://github.com/rdoc/rdoc/issues/317 ).

So the Tempfile.open method needs to be redefined to be understand by rdoc.

I've updated the pull request with the minimal change that will fix the
issue I don't like it as it define class methods outside of the class
itself (so the source is harder to read), and it hardcode the class name
two times (that I think is ugly).

I quite not understand why there is so much resistance to refactor the code
for readability.
