Re: Is this a bug in while-let or do I missunderstand it?

Hello,

Installed, thanks.  I edited your commit message to be more specific
about what you changed.

I realised though that we are missing one of the features of these
macros: you can also just write a symbol in the list, and it means to
proceed if that symbol is already bound to a true value.  E.g.

(let ((foo t))
  (when-let* ((hello "hello")
	      foo)
    (message hello)))

If in the first line you bind foo to nil instead, then 'message' is not
called.  I can't remember where this is documented, but it is somewhere..

It would be good to have it in the manual too, if you would consider
working on it.
