Here is the old fringe compensation code at work which apaprently adds 4
or 5 pixels to the specified value in order to get the sum of the widths
of the fringes equal to 7 (the frame's nominal character width). I
removed that code for NS on Emacs 25 but never did so for Emacs 24-4.
Even now I don't know whether it works correctly (see also bug #16856).
In any case I don't see why this should have any impact on what happens
in ansi-term. Apparently `term-window-width' kicks in and due to
(/= (frame-parameter nil 'right-fringe) 0))
it eventually stores in `term-width' a value that is one less than if
both fringes are present.
Since Eli now confirmed that what you observe is a result of one of his
fixes all I can suggest at the moment is to play with
(defun term-window-width ()
(if (and (not (featurep 'xemacs))
(display-graphic-p)
overflow-newline-into-fringe
(/= (frame-parameter nil 'right-fringe) 0))
(window-body-width)
(1- (window-body-width))))
What happens when you make it always return (window-body-width)?
(defun term-window-width ()
(window-body-width))
