* scanner.c (load_line): Add pbuflen argument, don't make
buflen static. If maxlen == 0 or preprocessor_flag,
don't truncate at buflen, but at maxlen. In xrealloc add
1 byte at the end for the terminating '\0'. Don't fill
with spaces up to buflen, but gfc_option.fixed_line_length.
(load_file): Adjust load_line caller. Add line_len variable.
* gfortran.dg/longline.f: New test.
