The commit 'ash,hush: set exit code 127 in "sh /does/not/exist" case'
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:

   $ )
   $ echo $?
   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:

    The commit 3c06acdac0b1ba0e0acdda513a57ee6e31385dce ([EXPAND]
    Split unquoted $@/$* correctly when IFS is set but empty) broke
    the case where $@ is in quotes and EXP_FULL is false.

    In that case we should still emit IFS as field splitting is not
    performed.

    [BUILTIN] Allow return in loop conditional to set exit status

    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=332954

    When return is used in a loop conditional the exit status will
    be lost because we always set the exit status at the end of the
    loop to that of the last command executed in the body.

    This is counterintuitive and contrary to what most other shells do.

    This patch fixes this by always preserving the exit status of
    return when it is used in a loop conditional.

    The patch was originally written by Gerrit Pape <pape@smarden.org>.
