I was wondering a bit why this is a problem in t0610, but not over here.
As far as I understand it these statements are fine in practice because
the expanded values cannot be split, right? So if "$1" expanded to
something with spaces in between things would start to break.
In any case, changing all of these to be quoted feels like the right
thing to do regardless of whether or not it happens to work with the
current values of "$1". Otherwise it's simply a confusing failure
waiting to happen.
