tail -1 -> tail -10 in documentation

[Paul Eggert]

I installed this in an attempt to keep up with the POSIX
interpretations process:

        * coreutils.texi (Standards conformance): Use "head -10" rather
        than "head -1" as example of obsolete usage, since the POSIX
        consensus is that "head -1" could be supported even if we don't
        yet have clear consensus on "head -10".  See today's revision to
        the SUS FAQ
        <http://www.opengroup.org/austin/papers/single_unix_faq.html>.
