4333 (read_original_directory): Don't back up when done.
4334 Don't clear no-longer used working_directory flag.

4345 (c_common_init): Update accordingly.
4346 (push_command_line_include): Don't cpp_push_main_file.
4347 Do LC_RENAME rather than LC_LEASE to get back to main file.
4348 Compared to pre-10-01 version, inline cpp_rename_to_main_file.
4349 (c_common_parse_file): Call cpp_read_main_file for subsequent main
4350 files, but call finish_options for all files.
4351 * c-opts.c (sanitize_cpp_opts): Don't set cpp_opts->working_directory.
4352 * fix-header.c (read_scan_file): Call cpp_read_main_file instead of
