The previous version of the doc strings seems to be more
straightforward.  Is there some subtlety that the new version tried to
get across?

!   "If non-nil, an active region takes control even if empty.
! This applies to certain commands which, in Transient Mark mode,
! apply to the active region if there is one.  If the setting is t,
! these commands apply to an empty active region if there is one.
! If the setting is nil, these commands treat an empty active
! region as if it were not active."

while it's now

(defcustom use-empty-active-region nil
  "Whether \"region-aware\" commands should act on empty regions.
If nil, region-aware commands treat empty regions as inactive.
If non-nil, region-aware commands treat the region as active as
long as the mark is active, even if the region is empty.

Region-aware commands are those that act on the region if it is
active and Transient Mark mode is enabled, and on the text near
point otherwise."
