":map! ^? ^D" works, contradicting the manual.  But like you say..

complicated.  Maybe in winter i find some time and try to write
a macro which looks for spaces and uses ^D if appropriate, maybe
temporarily a real, normal backspace can be "injected" for the
other cases.  I have no idea yet if such works in vile, but what
you say does not make me pretty confident.
Thanks anyway!
