It's also documented that { and } work with case, though I haven't
gotten into that habit yet (I've used it with for loops for about
6 years).

The question I have is why it doesn't also work with while, until,
and if/then/else?  Maybe people wouldn't think of sh as "the Algol
shell" if it were consistent on this point. ;-)
