Subject: 24.0.91; `region-active-p' definition
Date: Tue, 1 Nov 2011 10:12:45 -0700

The definition:
 
(defun region-active-p ()  "..."
  (and transient-mark-mode mark-active))
 
Makes no sense, AFAICT.  The mark *cannot* be active unless
`transient-mark-mode' is non-nil.  The very definitions of "active" mark
and "active" region imply transient mark mode.  When transient mark mode
is off, the region and mark are *never* active - the notion of "active"
does not exist in that context.
 
And since the correct definition: (defun region-active-p () mark-active)
is so trivial, this function should just be removed.
 
When is there ever any reason to test (and transient-mark-mode
mark-active)?  When is that value ever different from just the value of
mark-active?
