Problem reported by Andreas Schwab (Bug#37475). * doc/lispref/files.texi (Writing to Files) (Testing Accessibility, Kinds of Files): Document that accessibility and file-type predicates return nil if there is trouble determining accessibility or type. * etc/NEWS: Adjust, and list the affected primitives. * src/callproc.c (init_callproc): Go back to Ffile_exists_p. * src/fileio.c (PICKY_EACCES, file_test_errno): Remove. All uses removed. (Ffile_name_case_insensitive_p, Ffile_exists_p, Ffile_symlink_p) (Ffile_directory_p, Ffile_regular_p): Document that these functions return nil if there is trouble. (Ffile_name_case_insensitive_p, check_file_access) (Ffile_writable_p, Ffile_symlink_p, Ffile_directory_p) (Ffile_accessible_directory_p, Ffile_regular_p) * src/lread.c (Fload): Go back to treating trouble in determining the answer as if the file were missing. * src/fileio.c (Ffile_newer_than_file_p): Use file_attribute_errno not file_test_errno, since returning nil is not appropriate when there are two files to test; e.g., in the rare cases where both file timestamps have overflowed then neither t nor nil is correct.
