Does anyone know of a system for which `head -n1' doesn't work
the same as the traditional `head -1'?
The latter doesn't conform to POSIX 1003.1-2001.
Without this patch, dependencies don't work when
using `head' from the next test release of the GNU textutils
and with the `conform-to-latest-POSIX' switch set (via e.g.,
export _POSIX2_VERSION=200112).
I'll check it in if I don't hear anything by tomorrow.
