Why doesn't it use the `default' face? If no `face'
property is given to the string, why would the effective
face be something different from `default'?
Where in the doc do we say that this should use a face
that is used in an overlay placed on some buffer positions?
Is this behavior documented? I couldn't find anything
about it, but it might well be there somewhere. I looked
in the doc about overlays and the doc about the margin,
but perhaps it is there and I overlooked or misread it.
Or is this perhaps a bug? For what reason should the
properties of an overlay on some parts of a buffer
affect the appearance of the margin?
