It looks like ksh does the same thing if the expansion "fails" as it does if
any globbing fails:  it puts, and puts (no pun intended) things back to
normal.  {foo} "fails" because there's only one thing in the list, just as
"*asdf*" would "fail" in an empty directory.

Just my $0.02; it could honestly be a bug.  (I'm just justifying the current
behaviour, something that every software maintainance engineer delights in
8-).)
