Summary:                    ash: quoting rules for local variables different to
globals
Description: 
bash (and ash in 0.60) are happy with both

	var=`echo "a b c"`
	local var=`echo "a b c"`

(notice no double quotes around expression even though it expands to
multiple words.

ash in 1.0 requires quotes, but only for local variable declarations. The
attached file produces

	# sh test.sh
	this does work
	this

bash 2.05b produces

	# sh /tmp/test.sh
	this does work
	this should work

ash-local-fix.diff seems to fix the issue for me. I'm not sure of its
correctness however.

Nice try Rob but I've had ash SEGV since using this patch so I've had to
back it out.

This bug is really biting us, I use the construct

    local oldifs=$IFS

all over my code and it no longer works properly in ash 1.0, see attached
script and output.
