That looks fine.
Remaining: NEWS, coreutils.texi.
Also nice (it'd make less work for me) would be if you'd
follow the new guidelines in HACKING.
I.e., use "git format-patch ..." to create the patch,
ensure that "make check" and "make syntax-check" still succeed
with the very latest.
Neither is a must, but the closer it is to perfect,
the quicker it'll go in, because I won't have to find time
to adjust things.

It's to ensure that the right exit code makes it into the trap
code that cleans up. Look in "info autoconf" in the "Limitations of
Builtins" discussion of "trap".
