>Description:
Bug found by Christian Weisgerber <naddy@mips.inka.de> for FreeBSD. His description (taken from http://www.freebsd.org/cgi/query-pr.cgi?pr=30392) :

----
In here-documents, sh expands $? to the return value of the current
command rather than that of the previous command.

This behavior differs from that of all other Bourne family shells
I have tested (bash 2.05, ksh93 2001-07-04, pdksh 5.2.14, zsh 4.0.2,
Solaris 7 /usr/bin/sh and /usr/bin/ksh).

I noticed this because it breaks the evaluation of several
(non-critical) tests in the configure script of gtar 1.13.22.----


>How-To-Repeat:
------->
false
cat >>foo <<EOF
$?
EOF
cat foo
<-------

Returns 0 for NetBSD sh, 1 for all other shells.
