I seems that set-fringe-style insists on setting the sum of the widths
of the left and right fringe to a multiple of `(frame-char-width)',
but does so in a (for me) counterintuitive way.  If one can only set
the left and right fringe width width to a pair (l-allowed .
r-allowed) for which (% (+ l-allowed r-allowed) (frame-char-width)) is
zero, I would expect an arbitrary width pair (l . r) to be mapped a
pair (l-allowed . r-allowed) for which the Euclidean distance is
minimal.  This is not the case as, for example:

(l . r)  |-->  (l-allowed . r-allowed)

(0 . 0)  |-->  (0 . 0)
(0 . 1)  |-->  (0 . 11)
(1 . 1)  |-->  (5 . 6)

Shall we change the behavior of set-fringe-style so that it minimizes
the Euclidean distance?
