OK, I'll bite on this since it's my code originally.  :-)  I deliberately chose
not to break into subfunctions like X since the clarity of having the whole
implementation in one block seemed greater than that gained by splitting out. 
Also a number of redundancies in x_draw_bar_cursor() and x_draw_hollow_cursor()
are saved.  Opinions can vary, but calling one approach a "mess" while holding
the other up as a model seems a bit much, especially when long-function style is
used frequently throughout emacs.  I would say both could be improved.

As far as the width/cursor_width, maybe the parameter name could be changed to
"bar_cursor_width" or otherwise documented to indicate its intended use?
