b28d4c3462 ash: [VAR] Move unsetvar functionality into setvareq 
Upstream commit:

    Date: Tue, 25 May 2010 20:55:05 +0800
    [VAR] Move unsetvar functionality into setvareq

    This patch moves the unsetvar code into setvareq so that we can
    no have a pathological case of an unset variable hanging around
    unless it has a bit pinning it like VEXPORT.

only partly implemented the dash commit '[ERROR] Allow the originator
of EXERROR to set the exit status'.  This resulted in incorrect error
codes for a syntax error:

   $ )

   0

or a redirection error for a special builtin:

   $ rm -f xxx
   $ eval cat <xxx
   $ echo $?

350e686f3b ash: [PARSER] Recognise here-doc delimiters terminated by EOF 
Upstream commit 1:

    Date: Wed, 26 Sep 2007 17:14:16 +0800
    [PARSER] Recognise here-doc delimiters terminated by EOF

    Previously dash required a <newline> character to be present in order for
    a here-document delimiter to be detected.  Allowing EOF in the absence of
    a <newline> to play the same purpose allows some intuitive scripts to
    succeed.  POSIX seems to be silence on this so this should be OK.

    Test case:

        eval 'cat <<- NOT
                test
        NOT'
        echo OK

    Old result:

        test
        NOTOK

    New result:

        test
        OK

Upstream commit 2:

    Date: Sat, 20 Oct 2007 18:49:31 +0800
    [PARSER] Fix here-doc corruption

    The change

        [PARSER] Recognise here-doc delimiters terminated by EOF

    introduced a regerssion whereby lines starting with eofmark but are not equal
    to eofmark would be corrupted.  This patch fixes it.

    Test case:

        cat << _ACEOF
        _ASBOX
        _ACEOF

    Old result:

        SASBOX

    New result:

    [PARSER] Fix parsing of ${##1}

    Previously dash treated ${##1} as a length operation.  This patch fixes that.

    Test case:

        set -- a
        echo ${##1}OK

    Old result:

        1OK

    New result:

This was a real bug in ash (but not in hush).
