It looks like there are a couple of other instances of the potentially empty braces problem in this script, so we could address them at the same time just in case.
Also, if the variable somehow ended up containing just whitespace then
the proposed fix would fail.
How about just adding : to each brace, as in the following patch.
(can always put the : on a line of its own, if people think tacking it
on the brace line is confusing, but it struck me as a waste of space)
