Re: customize - convenience group changes frame fringe setting

[Richard Stallman]

    I thought there were two issues:

     - Clicking a customize navigational button loaded some code, which turned
    on fringe-mode. To me, that is just a bug: fringe-mode should not be turned
    on that way. Navigational buttons can load code, if they need to, but they
    should not affect the user experience beyond navigation.

     - If the user (in some other way) asks to turn on fringe-mode, does that
    apply only to the selected frame or to the default-frame-alist? That is, is
    he asking to add fringe to one frame or to all frames going forward?

Those issues are easy or already decided.  The hard issue is this one:

What should fringe-mode mean if the user has put things in
default-frame-alist that nullify the effect of fringe-mode?
