1. If you use the mouse to select text, then having the region size always
visisble (when active) means not having to use `M-=': double-click + click,
or drag a region - you see how big it is as you drag.

2. In transient mark mode, when you use `C-SPC' the region becomes active,
even though it is empty. This mode-line indicator shows you that the region
is active even when you can't see it. When a command (e.g. query-replace)
limits itself to the region, this helps you avoid the exercise of figuring
out that you are acting on an empty region.

This indicator is helpful mainly for someone who uses transient mark mode
(it appears only when the region is active). If you don't use transient mark
mode, you likely won't see the point.
