Hi Rob,

Thanks for the heads-up.
That is indeed my mistake.

I ran "git syncsub" vs. a local gnulib repository
in which I had committed-but-not-pushed a change.

We now have a public-submodule-commit make target in the gnulib-provided
maint.mk, and it checks for just that condition.  However, it is currently
run only at release time.  This makes it apparent that we should check
this all the time...  At least via "make distcheck", and probably via a
server-side hook to prevent the offending "push" as well.

I've just updated (careful to use a public commit,
not the mountlist pair that is waiting for an ACK ;-)
and pushed the fix:

Subject: [PATCH] build: update gnulib submodule to latest

The previous gnulib submodule reference was to a non-public commit.
