(final-before-7.2?) snapshot imminent

[Jim Meyering]

I'm about to make a snapshot with the latest from coreutils and from gnulib.
Other than a minor test failure affecting install's new -C option that
may be unreproducible (thanks for all the attempts, Kamil!),
I think there's nothing else I wanted to fix.

Expect a new snapshot in the next hour or so, and a release
of coreutils-7.2 possibly as early as the end of tomorrow.
