[Boehne, Robert]

Paul,

I've approved this patch, and am checking it in to the relevant
branches.

Thanks,

        * ltmain.in: Don't assume that "sort +2" works, as POSIX
        1003.1-2001 says that "sort +2" is supposed to sort the file
        named "+2".  An example host that behaves like this is
        textutils 2.0.21 with _POSIX2_VERSION=200112.
