date: fails to diagnose invalid input

date -d "$(printf '\xb0')" would print 00:00:00 with today's date
rather than diagnosing the invalid input.  Now it reports this:
date: invalid date '\260'
* gnulib: Update submodule to latest for fixed parse-datetime.y.
* tests/misc/date [invalid-high-bit-set]: New test.
* NEWS (Bug fixes): Mention it.
* bootstrap, tests/init.sh: Also update to latest.

   head --lines=-N (-n-N) now resets the read pointer of a seekable input file.
   This means that "head -n-3" no longer consumes all of its input, and lines
   not output by head may be processed by other programs.  For example, this
