Documentation

Whether "region-aware" commands should act on empty regions.

If nil, region-aware commands treat the empty region 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.

This variable was added, or its default value changed, in Emacs 23.1.

Probably introduced at or before Emacs version 23.1.
