Subject: 29.0.60; while-let uses if-let* convention in contradiction to the docstring

The docstring of `while-let' says:

     The variable list SPEC is the same as in if-let.

However in the definition `if-let*' is used. `if-let*' differs from
`if-let' since it doesn't support the special single binding form.

     (while-let (var exp)
         ...)

Therefore `if-let*' should be replaced with `if-let' in the definition
of `while-let', bringing the implementation in accordance with the
docstring. The name `while-let' (in contrast to `while-let*') also
suggest that the `if-let' spec is supported.
