Subject: * lisp/emacs-lisp/syntax.el (syntax-propertize-rules): Use `macroexp-let2`
X-Git-Tag: emacs-28.0.90~3307
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=7109307c1a62fb3ab781989d495bacd3c2b15a2e;p=emacs.git

* lisp/emacs-lisp/syntax.el (syntax-propertize-rules): Use `macroexp-let2`

This also silences the recently introduced compilation warning.
