I have the vague impression of having already seen such a bug-report,
except the other way around (where the user complained that the
wrap-prefix was displayed in the font that happened to be active where
the line got truncated), so we "fixed" it for Emacs-24.

At least that was within the redisplay engine.  So maybe the problem we
have now is that adaptive-wrap constructs the prefix without paying
attention to existing faces.
