[coreutils] [PATCH] Fix typo in texinfo annotation.

[Ralf Wildenhues]

* doc/coreutils.texi (sort invocation): Use @pxref inside parentheses.
---

Hi coreutils maintainers,

this trivial patch avoids this warning from CVS texinfo's makeinfo:

coreutils.texi:3807: warning: `.' or `,' must follow @xref, not `)'.
coreutils.texi:3807: warning: for cross-references in parentheses, use @pxref.

Cheers,
Ralf
