Re: fringe bugs and issues (and a couple display margin bugs)

[Richard Stallman]

    Normally, I would set a breakpoint on a specific line of a specific
    file - and as a reminder, gud could put a marker on that line in
    the display margin - something an IDE debugger commonly does.
    If display margins are not the right tool for that, well...

I see.  Yes that could be a good use for the display margins.

With this use, it would be more natural for the fringes to be inside the
display margins.  Thus far, that arrangement seems more natural for all
the uses we have considered.
