Patch 7.0.155
Problem:    When getchar() returns a mouse button click there is no way to get
            the mouse coordinates.
Solution:   Add v:mouse_win, v:mouse_lnum and v:mouse_col.

+ 		When the user clicks a mouse button, the mouse event will be

  		There is no prompt, you will somehow have to make clear to the
  		user that a character has to be typed.
  		There is no mapping for the character.
