Good lord - you don't need to use arrays for this.
The old-fashioned ways have their ways. Both the 'set'
command and the 'read' command can split args and assign
to distinct variable names.
Try something like the following:
diff-tree -r $id1 $id2 |
sed -e '/^</ { N; s/\n>/ / }' -e 's/./& /' |
while read op mode1 sha1 name1 mode2 sha2 name2
do
... various common stuff ...
case "$op" in
"+")
...
;;
"-")
...
;;
"<")
test $name1 = $name2 || die mismatched names
label1=$(mkbanner "$loc1" $id1 "$name1" $mode1 $sha1)
label2=$(mkbanner "$loc2" $id2 "$name1" $mode2 $sha2)
diff -L "$label1" -L "$label2" -u "$loc1" "$loc2"
;;
esac
done

I won't rest till it's the best ...
