enable non-integer ranges as indices by default and deprecate preference * octave.cc (maximum_braindamage): Don't call Fdo_brainded_shortcircuit_evaluation. * error.cc (initialize_default_warning_state): Don't set Octave:noninteger-range-as-index to "error". * octave.cc (maximum_braindamage): Don't call Fallow_noninteger_range_as_index. Don't set Octave:noninteger-range-as-index to "on". * ov-range.h, ov-range.cc (Vallow_noninteger_range_as_index): Now static. Set default value to true. * ov.h (octave_value::index_vector): New arg, require_integers. * ov-base.cc, ov-base.h (octave_value::index_vector): Likewise. * ov-base-diag.cc, ov-base-diag.h, ov-bool-mat.h, ov-bool-sparse.h, ov-bool.h, ov-ch-mat.cc, ov-ch-mat.h, ov-class.cc, ov-class.h, ov-colon.h, ov-complex.h, ov-float.h, ov-flt-re-mat.h, ov-intx.h, ov-lazy-idx.h, ov-perm.cc, ov-perm.h, ov-range.cc, ov-range.h, ov-re-mat.h, ov-re-sparse.cc, ov-re-sparse.h, ov-scalar.h: Make corresponding changes in all derived methods. * ov-range.cc (octave_range::index_vector): If new require_integers argument is true, also require integer arguments regardless of the setting of Vallow_noninteger_range_as_index. * utils.cc (Fisindex): Don't temporarily set Vallow_noninteger_range_as_index. Call index_vector with argument of true. * NEWS: Mention change in default value, warning state and deprecated function.
