Currently the statusline in mg shows the line and column numbers, which is
nice but doesn't let you know your relative position in the file.
Emacs shows 'top', 'bot', 'all' or your relative position like '42%'. This
diff implements that behaviour in mg too.
From:
(fundamental-fill)--L3--C31
to:
(fundamental-fill)--9%--L69--C0
or
(fundamental-fill)--all--L1--C0
you get the idea.
