I made this syntax work for `cl-flet`, so I'm not opposed to allowing it
for `cl-macrolet` and `cl-labels`.

BTW, when I added it to `cl-flet` the main purpose wasn't to
write `(cl-flet ((f (lambda ...))) ...)` but rather to write
`(cl-flet ((f x)) ...)` or more generally to compute at runtime which
function to bind to `f`, without having to introduce an η-redex.

As for indentation, I consider the way we currently indent `cl-labels`
and friends as a bug.
