gnu-diff.sh patch

'ello

Any objections on me applying this fix for gnu-diff.sh? It corrects:

 1. Test command's stderr no longer pollutes the configure output

 2. The GNU diff selection now picks the *FIRST* GNU diff command that
    matches the criteria, instead of the last as it currently does!

 3. It also makes it stop searching through the path as soon as it found one
    diff that works.
