Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>

    Pacify byte-compiler for with-wrapper-hook
    
    * lisp/subr.el (subr--with-wrapper-hook-no-warnings):
    New macro, split out from with-wrapper-hook.
    * lisp/abbrev.el (abbrev--default-expand):
    * lisp/minibuffer.el (completion--in-region):
    * lisp/simple.el (buffer-substring--filter):
    * lisp/subr.el (with-wrapper-hook):
    Use it.
