You're right, it doesn't mean anything, the fringe width will depend on
the frame that it's displayed in.

I assumed that all frames have the same fringe width, which was previously
true by default, so I didn't notice a problem.  The default value for the
speedbar is 0 now, which isn't generally what I want.

If the buffers that hold breakpoint icons are visible, it's straightforward.
If they are not visible then I'm not sure what to do.
