vertical bar between windows disrupts my view

[Joe Corneli]

I'm writing this message with my screen split in two vertically;
there are two windows on the screen.  The mail buffer is in the one
on the right.

The problem that I'm experiencing is that the one-pixel-wide white
line that demarcates the border between the right-hand window and
the lefthand window actually takes up the first column of pixels in
the right-hand window.  So, for example, if I 

(set-frame-font "-misc-fixed-medium-r-*-*-13-*-*-*-*-*-*-*") 

then characters like `p' and `b' that appear in the first column of
the mail buffer look weird, because their ascenders and decenders
are hidden by the vertical white line.

You can try this in you Emacs now:

p
b

If I kill the other window, then the ascenders and decenders in
question appear in the first column of pixels visible on the screen,
and they are not obstructed from view.

It seems that there should be one more pixel of padding in the
window on the right of a vertically split screen.
