[git commit] hush: push down expansion var in handle_dollar()

[Mike Frysinger]

commit: http://git.busybox.net/busybox/commit/?id=ef3e7fdd3b18ef3c43a58a06251eaf615e18a789
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master


Declare the variable in the scope it is used rather than the entire
function scope so it's obvious it is only used there.
