Looking at coreutils' ls.c, I notice that the substitution of ? for
"funny" characters and the quoting style are orthogonal, because the
quoting style will not (always) prevent control characters being sent
to the terminal.

Thus the control of the quoting style and the control of
?-substitution are separate.  It might make sense to do something
similar in findutils, but perhaps that's an unneccesary complexity.
