But setting it to nil does not remove the fringe (0 does).
Nil restores the default width which - as I interpret it - is the
minimum width necessary to display any of the currently defined fringe
bitmaps (i.e. min. 8 pixels with the current bitmaps).
Once it is possible to redefine those bitmaps externally, it would
also be possible to define a bitmap which is wider than 8 pixels - and
the default should [IMO] be to automatically adjust the fringe width
to allow the wider bitmap to be displayed.
So nil is the actual value meaning : "just wide enough".

Thank you Gerd - I already received a complaint about a display problem
caused by my changes, so you saved my day!
