I was going to acquire the width and height of a character the cursor
is over, by using the following code:
(posn-object-width-height (posn-at-point))
However, I found that this code gives back a wrong result when a
header line is displayed such as tabbar-mode. This code returns the
size of another character, which is in the position different from the
exact one in the number of objects included in the header line.
For example, when the cursor is in the top left corner of the window,
the size of the object in the left end of the header line is obtained.
Steps to reproduce:
1. Turn on tabbar-mode.
2. Evaluate the following expressions in *scratch*:
(defun char-w-h ()
(message "%s" (posn-object-width-height (posn-at-point))))
(add-hook 'post-command-hook 'char-w-h)
3. Move a cursor from place to place in the window.
