new octave_value functions for formatting output * ov.h, ov.cc, ov-base.h, ov-base.cc, and numeric/matrix-like objects: (get_edit_display_format): New function. (edit_display): Pass float_display_format as argument. * pr-output.h, pr-output.cc: New variants of the octave_print_internal functions that accept display formats. Expose functions for getting display formats. * variable-editor-model.cc: Maintain display format for model.
