fbac2e9de2 Fixed new bug the previous fix introduced:
false
    foo=bar
    echo $?

would print 1
Also fixed the long standing bug:

    false
    echo `echo $?`

would print 0
The exitstatus needs rethinking and rewriting. The trial and error method
is not very efficient

5c42185b5c Oops... typo in the IFS previous fix. 1995-02-28 23:27:24 +00:00

6ab1954578 Changed so that backquote expansion eats all trailing newlines, not just
the last one.
Reported by guido@gvr.win.tue.nl (Guido van Rooij).
Repeat By:

	echo "`cat file-with-many-newlines`"

3936aab031 Changed IFS string-splitting so that it breaks spaces even when IFS does not
begin with a space, but contains one. Fixes PR bin/809.

        #!/bin/sh
        list="a  b c "
        echo "With ordinary IFS"
        for i in $list;do
            echo $i
        done
        IFS=":${IFS}"
        echo "With changed IFS"
        for i in $list;do
            echo $i
        done

Note that before the fix ":${IFS}" behaved differently than "${IFS}:".

${#WORD}
    ${WORD%PAT}
    ${WORD%%PAT}
    ${WORD#PAT}
    ${WORD##PAT}

718ac53f6f evalvar(): If subtype is VSASSIGN (or VSQUESTION), argstr() already rolled
forward the backquote queue.  If VSQUESTION it doesn't matter because we
already exited with an error.
