Make sure they can't be valid chars, so they don't overlap with char codes.
Use an enum instead of a lot of #defines.
(long_options, main, usage): Remove --ending-file option.
(OPTION_STRING): Remove -E.
(ISODIGIT, ISSPACE): Remove; now in system.h.
(read_and): Excise ending_file_option.
(decode_header): No need to AND mode with 07777; MODE_FROM_OCT
does this now.
(from_oct): Cast ISSPACE arg to unsigned char.
(mode_from_oct): Translate modes from external to internal form.
Do not complain about unrecognized mode bits.
(decode_mode): Do not assume mode bits have traditional Unix values.
Do not assume mode bits have traditional Unix values.
(set_mode): Use %04 not %0.4 format.
(extract_sparse_file): Do not use data_block uninitialized.
Check for lseek failures; use portable lseek whence values.

(start_header): Do not assume mode bits have traditional Unix values.
(finish_sparse_file): Use lseek whence macros instead of integers.
(dump_file): Do not assume mode bits have traditional Unix values.
Do not invoke finish_sparse_file on a negative file descriptor.
(child_open_for_compress, flush_write, flush_read): Use it to write
buffers.
(open_archive): Report error if fstat of archive fails.
Improve efficiency of check for /dev/null.
Also, fix some corner cases with remote archives and /dev/null checking.
(close_archive): Test for input fifo only if not remote.
Truncate output archive only if it's not remote.
Output a trailing NUL unless the value won't fit without it;
this is backward compatible with Unix tar (and with GNU Emacs).
(finish_header): No need to append NUL to chksum, now that
to_oct is doing it.
(intconv): Remove; use xstrto* fns instead.
("xstrtol.h"): Include.
(check_decimal): Remove.
(long_options, usage, OPTION_STRING, decode_options):
Remove -y, --bzip2, --unbzip2.
(decode_options): Use xget_version instead of get_version.
Check for overflow with -b and -L and RECORD_SIZE_OPTION.
Replace invocations of check_decimal with xstrtoumax.
(from_oct): Add forward decl.
(read_header): Return HEADER_FAILURE if we can't parse the checksum.
(from_oct): Report an error only if TYPE is nonzero.
Quote any funny characters in bad header.
when the original value is out of range. Do not append a space to the
output; modern tars don't. When a value is out of range, specify the
maximum value, not the number of bits.
(GID_NOBODY, UID_NOBODY): New macros.
(gid_to_oct, uid_to_oct): Use them as substitutes.
(finish_header): Do not assume that UINTMAX_TO_OCT appends a space.
(dump_file): Check whether the file changed as we read it.
size_from_oct, time_from_oct, uid_from_oct, uintmax_from_oct):
Use TYPE_MAXIMUM instead of macros like OFF_MAX, which are not reliable
(e.g. OFF_MAX in AIX 4.2 is incorrect).
giving name of type of octal field, for error messages. Report an
error if the value is too large to fit in the field.
(gid_to_oct, major_to_oct, minor_to_oct, mode_to_oct, off_to_oct,
size_to_oct, time_to_oct, uid_to_oct, uintmax_to_oct): New functions.
(write_eot, write_long, finish_header, deal_with_sparse,
finish_sparse_file, dump_file): Use dev_t, off_t, ssize_t, size_t when
appropriate. Remove now-useless casts. Use unsigned long to print
*_t types, except use STRINGIFY_BIGINT for off_t.
(find_new_file_size): 1st arg is now off_t*.
(finish_sparse_file): Args now use off_t, not long.
Check for lseek error.
(create_archive, dump_file): Cast -1 to dev_t when necessary.
(dump_file): Device arg is now dev_t.
Avoid overflow when testing whether file has holes
by using the new ST_NBLOCKSIZE macro.
real_s_sizeleft, current_block_ordinal): Now off_t.
(write_error): Arg is now ssize_t.
(child_pid): Now pid_t.
(available_space_after): Now size_t.
(child_open_for_compress, child_open_for_uncompress, flush_write,
open_archive, flush_write, write_error, flush_read, close_archive):
Use pid_t, ssize_t, size_t when appropriate. Remove now-useless
casts. Use unsigned long to print *_t types, except use
STRINGIFY_BIGINT for off_t.
print_for_mkdir): Use mode_t, off_t, size_t when appropriate. Remove
now-useless casts. Use unsigned long to print *_t types, except use
STRINGIFY_BIGINT for off_t.
(read_header): Check for overflow when converting header size.
(from_oct): Now static. Now returns uintmax_t. `where' arg is now
const char *. Size arg is now size_t. Now takes new type and maxval
args. Compute result using uintmax_t, not long. Report error if
field does not contain octal number in range.
(gid_from_oct, major_from_oct, minor_from_oct, mode_from_oct,
off_from_oct, size_from_oct, time_from_oct, uid_from_oct,
uintmax_from_oct): New functions.
(stringify_uintmax_t_backwards): New function.
(decode_mode, print_for_mkdir): Mode arg is now mode_t.
(skip_file): Offset arg is now off_t.
