	PR libfortran/38199
	* io/read.c (read_decimal): Quickly skip spaces to avoid calls
	to next_char.
	* io/unit.c (is_trim_ok): New helper function to check various
	conditions to see if its OK to trim the internal unit string.
	(get_internal_unit): Use LEN_TRIM to shorten selected internal
	unit strings for optimizing READ. Enable this optimization for
	formatted READ.
	* io/list_read.c (finish_list_read): Don't call eat_line for
	internal units.
