FYI I applied the new patch and started the rebuilt Emacs with my
initializations, which contain this:

(modify-frame-parameters nil '((width . 85) (fullscreen . fullheight)))

However, window-width in fact returned 73 (but window-height was the full
height).  Then I evalled this:

(modify-frame-parameters nil '((width . 85)))

Now, window-width was 78.  (Maybe the increase despite the same passed
width value is because I customize the tool bar to appear on the left
side, and maybe that takes effect after the initial frame width is set.)
To get a window-width of 85 columns, I had to give the width
frame-parameter a value of 92.

This is with the xft backend and font
