(That matches the > first sample text above, too.) Could you please provide a complete self-contained recipe for reproducing this? Something like this: - start with "emacs -Q" - enlarge the font by shift-mouse and selecting "Increase Buffer Text Size" N times (please tell what is the value of N) - type the following text: .... etc. Given your description, I have hard time understanding what to do to reproduce this. Thanks.
