... And so if one wants zero redirects, one should set max_redirect to 1 really ...

NO, that's wrong. Use only  requests_redirectable method.

    imho, max_redirect => 0 should not warn. I'm with AnonyMonk above in that this smells like a bug (whether doc or code, I digress).

    If a parameter such as one that has "max" in its name is set to zero, it should not trigger a warning like this.

    Perhaps there's a good reason for it, but that would make it a doc bug. Otherwise, if I say "max something is zero", then any warnings/errors should be ignored, which would be a code bug.

    After a cursory review, the documentation does not handle this situation, and it should.
