The special case of a SPEC of the form (SYMBOL SOMETHING) is supported
only for backward compatibility by `if-let'.  We wanted to get rid of
this special syntax anomaly.

So it makes no sense to add this syntax to newly introduced macros.  We
should fix the docstring of `while-let' instead - unless the goal of
getting rid of this syntax has changed.  But then we should have a
discussion first.  Instead it seems you just reverted a change by Lars
that was the result of a discussion in emacs-dev.
