[racket] case-lam structure allowing indirects?

I'm using Racket 5.0.1 and the compiler/zo-parse module.  On some of
the structures I'm getting back, I'm seeing that a case-lam structure
has a clause that's an indirect, rather than a lam.  The documentation
for 5.0.1 says that a clause has to be a lam though.  Is this
intentional?
