Missing ChangeLog plus mail abbrev problem

[Chong Yidong]

Hi Stefan, your following checkin lacks a ChangeLog entry:

  * abbrev.el (abbrev-with-wrapper-hook): (re)move...
  * simple.el (with-wrapper-hook): ...to here.  Add argument `args'.
  * minibuffer.el (completion-in-region-functions): New hook.
  (completion-in-region): New function.
  * emacs-lisp/lisp.el (lisp-complete-symbol):
  * pcomplete.el (pcomplete-std-complete): Use it.

I think this checkin is also the culprit for a mailabbrev error.  To
reproduce,

M-x message-mail RET
C->
a,
Debugger entered--Lisp error: (wrong-number-of-arguments ...
  ...
