master 33a52cb: Give 'when-let' and 'when-let*' their own Edebug specification.

[Philipp Stephani]

branch: master
commit 33a52cb45832d4041b6f0db78ee289ba9aca0f64
Author: Philipp Stephani <phst@google.com>
Commit: Philipp Stephani <phst@google.com>

    Give 'when-let' and 'when-let*' their own Edebug specification.
    
    The Edebug specification of 'if-let' and 'if-let*' doesn't work if the
    body is empty.  While that's a pathological case, it's not wrong per
    se, and could arguably happen due to macro expansion.
    
    * lisp/emacs-lisp/subr-x.el (when-let*, when-let): Don't reuse Edebug
    specification from 'if-let*' and 'if-let'.
