Set $IFS to newline, so that $(git diff --name-only ...) output is
split at record boundaries, not inside pathnames?

A quick experiment you can do to convince yourself may be:

-- >8 --
#!/bin/sh

data () {
	echo "a"
	echo "b c" ;# SP in between
	echo "d	e " ;# HT and trailing SP
}

show () {
	for i
	do
		echo "<<$i>>"
	done
}

echo ONE
show $(data)

IFS='
'

echo TWO
show $(data)
-- 8< --

On the "git archive" invocation, there may be something that tells
the pathspecs are literal, like '--literal-pathspecs' option, to
avoid metacharacters from being expanded, though.
