findutils 4.1.6: -prune suppresses implicit -print

[Andreas Schwab]

Since -prune is now considered to have side effects it will prevent the
implicit addition of -print.  IMHO this is a bug, since -prune does not
make any output, contrary to all other places where size_effects is set.
There should be a distinction between having a side effect in general
effect (in the meaning it must not be moved in opt_expr) and producing
some output, and only in the latter case the implict -print should be
suppressed.

Andreas.
