Prints first 98, = then 119

Why do you think this = is a bug?

I thought the pixel = width shouldn=E2=80=99t include the line-prefix?

It should.  =46rom the = function's doc string:

This function = exists to allow Lisp programs to adjust the dimensions
of = WINDOW to the buffer text it needs to display.

When you want to know how wide a window you need for = displaying some

I see. I = managed to use (window-text-pixel-size nil (point) (point)) to calculate = the prefix width and subtract it out. Thanks.
