The answer is in `modeline-region.el', here:
https://www.emacswiki.org/emacs/download/modeline-region.el
It's described here:
https://www.emacswiki.org/emacs/ModeLineRegion
As for what indication you get for an empty but
active region: that's controlled by user option
`mlr-empty-region-flag'. By default its value
is non-nil, which means that you see this in
the mode-line:
0 lines, 0 chars
That's highlighted there with face `mlr-region',
which by default just inherits from face `region'.
If you customize the option to nil then you see
no mode-line indication that the region is empty
and activated.
(You still get the message "Mark set", of course,
when you use `C-SPC', so at least you get some
notification of that action.)
