improve formatting of large values in pr-output functions
* pr-output.cc (make_real_format): Initialize local variables.
Switch to E format if available precision is exceeded. Set int format
based on leading digits.
(make_complex_matrix_format): Also allow switching to E format if
printing in fixed_point_format. Set int format based on leading
digits.
(make_real_matrix_format, make_complex_format,
make_complex_matrix_format, make_range_format):
Initialize local variables.
