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}:".

4aece6a461 Renamed builtins to builtins.def to eliminate make's (incorrect) circular
dependancy between the builtins data file and builtins.c.

The bug only occured when there was no obj directory, and is a result of
NetBSD's better (compared to 4.4lite's) default make rules.

Fixes bug #301.
