* io/write.c: Cleaned up whitespace.
(write_d, write_e, write_f, write_es, write_en): Use new helper function
write_float_0. (write_float_0): New helper function.
(get_precision, select_buffer, select_string, write_float_string): New
helper functions used in remaining float writing functions. Helper function
write_float_string now contains code for writing to kind=4 character
internal units.
(write_real): Modified to establish working buffers at this level and to
use new helper functions.
(write_real_g0): Likewise modified.
(write_complex): Likewise modified. Gets both float strings before
output so that final lengths can be determined which allows right
justifying the complex number with no intervening spaces.
* io/write_float.def (build_float_string): Renamed from previosly
output_float, modified to use buffers passed in from higher functions,
builds a null terminated string of the floating point value. Character
kind=4 code eliminated.
(write_infnan): Likewise modified to use incoming buffers and eliminate
kind=4 related code.
(OUTPUT_FLOAT_FMT_G): Deleted, functionality moved into FORMAT_FLOAT.
(FORMAT_FLOAT): Renamed macro from WRITE_FLOAT. Use build_float_string.
(get_float_string): Renamed from write_float, uses FORMAT_FLOAT macro.
Buffer allocation removed, now at higher level.
