	Now that we're marking file descriptors as CLOEXEC in savefd, we no longer
	need to close them on exec or in setinputfd.

ea7d2f6ec0 ash: fix error code regression 
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 $?
   0

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:

        _ASBOX

Upstream commit:

    Date: Thu, 4 Oct 2007 22:15:10 +0800
    [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:

        OK

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