[PATCH] Fix /bin/sh behaviour with 'here document'

[Andy Shevchenko <andy.shevchenko%gmail.com@localhost>]

Simple script
  cat << xx
  Test
  xx
w/o <newline> at the end of file produces incorrect output like
  Test
  xx
in /bin/sh. /usr/pkg/bin/bash works normally. Although the SuSv3 in 2.7.4
somehow requires a <newline>, the actual file or stream could be ended by EOF
w/o <newline>. Probably EOF has higher priority, but I don't know. Actually the
only two shells what I saw have described behaviour: from NetBSD and from old
Ubuntu. New ones consider <newline> at the end of file like recommended.
