The overlay doesn't seem to appear for me, for some reason.

Could you please post a recipe that doesn't require Flymake?  Surely,
creating an overlay doesn't require such heavy machinery?  I tried to
put a simple overlay with before-string in a buffer, but didn't see
any problem with the Y coordinate reported by posn-at-point, so I
guess there's a need in something special in that overlay.

Thanks.
