[PATCH] git-am: head -1 is obsolete and doesn't work on some new systems

From: Alejandro Mery <amery@geeks.cl>
Date: Jun 17, 2008, 11:43 UTC
Message-ID: <4857A37D.8040004@geeks.cl>

head -<n> was deprecated by POSIX, and as modern versions of coreutils package don't support it at least one exports _POSIX2_VERSION=199209 it's fails on some systems.

head -n<n> is portable, but sed <n>q is even more.
