ash: [REDIR] Remove redundant CLOEXEC calls
Upstream commit:
Now that we're marking file descriptors as CLOEXEC in savefd, we no longer
need to close them on exec or in setinputfd.
but it missed one place where we don't set CLOEXEC. Fixing this.

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

Also add tests. wait5.tests so far fails (but works for ash and dash).

[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

[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

[PARSER] Fix parsing of ${##1}
Previously dash treated ${##1} as a length operation. This patch fixes that.
Test case:

echo ${##1}OK
Old result:

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

expand: Fixed "$@" expansion when EXP_FULL is false
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.

This is obviously wrong. This patch fixes that.

[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>.
