b05a103ea7 Move the when-let family of macros to subr.el 
* lisp/subr.el (internal--build-binding)
(internal--build-bindings): Moved from subr-x.el and rewritten to
not use the threading macro.

uses these macros in functions that end up being called during
bootstrap.

84e207c811 * lisp/emacs-lisp/subr-x.el (if-let*, if-let): Use looser Edebug spec 
This makes the same spec work both for `if-let` and `when-let`.

(when-let*, and-let*, when-let): Simplify accordingly.
 2021-05-22 10:21:59 -04:00

33a52cb458 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'.
