Remove all blank lines with "format compact" * pr-output.h (Vcompact_format): New global variable. * pr-output.cc (Vcompact_format): No longer a static variable. (pr_scale_header, pr_col_num_header, octave_print_internal): Use Vcompact_format to eliminate some newlines. (Vformat): Document this change. * ov-base.cc (octave_base_value::print_name_tag, octave_base_value::print_with_name): Use Vcompact_format variable to omit newlines. * ov-class.cc (octave_class::print_name_tag): Ditto. * ov-range.cc (octave_range::print_name_tag): Ditto. * ov-struct.cc (octave_scalar_struct::print_raw): Ditto.
