FWIW, Automake removed all uses of `head' and `tail' last year.

        * lib/depcomp: Don't use "tail +3"; it's not portable to
        POSIX 1003.1-2001 hosts.

        * tests/cond12.test: Use sed 1q, not `head -n 1'.
        The latter is not portable to some old systems.
        * m4/depout.m4: Don't use `head -1'; it's no longer portable.
        Use `sed 1q' instead.
        * tests/insthook.test: Likewise.
