This actually was pretty helpful.  The problem is, of course, that I
can't rewrite all of my source code to be in 65-width lines, nor can I
convince my colleagues to do so.

So what I need now is some way to fix the verbatim environments that are
produced by org-mode to use a smaller font.  I.e., instead of trying to
fix the source code to match char-width, fix the char-width to match the
source code.  Any idea how to do that?
