[REPOST PATCH xauth] Don't crash when running past the end of the chain

[Alan Coopersmith]

When there were complaints last year that no one was integrating xauth patches
since there was no maintainer, he volunteered to maintain it, so I let him try.

(Yes, we're desperate enough for maintainers to consider taking volunteers - if
  it's not making any difference, we're not likely to repeat the experiment.)
