runtime(doc): clarify documentation for "v" position at line()
Problem: the previous documentation falsely states that "v" always
refers to the start of a visual area. In fact, the reference of "v" and
"." complement each other. If the cursor is at the start of
a (characterwise) visual area, then "v" refers to the end of the area.
Solution: be more verbose and explicit about the connection between "."
and "v" and also refer to |v_o| which many vim users will be familiar
with for visual areas.

+ v When not in Visual mode, returns the cursor

+ this is that in Visual mode "v" and "." complement
+ each other. While "." refers to the cursor
+ position, "v" refers to where |v_o| would move the
+ cursor. As a result, you can use "v" and "."
+ together to work on all of a selection in
+ characterwise visual mode. If the cursor is at
+ the end of a characterwise visual area, "v" refers
+ to the start of the same visual area. And if the
+ cursor is at the start of a characterwise visual
+ area, "v" refers to the end of the same visual
+ area. "v" differs from |'<| and |'>| in that it's
+ updated right away.
Note that a mark in another file can be used. The line number
then applies to another buffer.
