restore auto switch to E formats octave_print_internal functions
* pr-output.cc (pr_output_traits::max_field_width): New variable.
(make_real_format, make_real_matrix_format, make_complex_format,
make_complex_matrix_format, make_range_format): Switch to E format if
computed field width exceeds max field width for type or if computed
number of digits to display exceeds max meaningful digits for type.
