("human.h"): Include.
(LONGEST_HUMAN_READABLE, enum Output_units): Remove.
(count_entry): Now returns uintmax_t, not long.
(human_readable_base): Renamed from opt_human_readable; value is now
zero or positive integer, not just zero or nonzero.
(output_units): Now an integer giving output size.
(tot_size): Now uintmax_t, not long.
(long_options, usage): Add --si or -H.
(main): Adjust to renamed option variables.
Use -H if BLOCKSIZE is SI. Add -H.
(human_readable): Remove; rewritten and now in lib/human.c.
(print_size): Rewrite in terms of human_readable.
Accept extra arg to be printed after size; all callers changed.
("human.h"): Include.
(LONGEST_HUMAN_READABLE_1K_BYTE_BLOCKS): Remove.
(human_readable_base): Renamed from human_blocks; value is now
zero or positive integer, not just zero or nonzero.
(output_units): New variable;
replaces booleans kilobyte_blocks and megabyte_blocks.
(long_options): Add --si or -H.
(print_header): Adjust to renamed option variables.
(human_readable_1k_blocks): Remove.
(show_dev): Count blocks using uintmax_t, not long.
Calculate percentages using double, not long; this still isn't
perfect as it suffers double rounding, but it's more likely to
round correctly in practice than using long did.
Adjust to renamed option variables.
Use new human_readable library function to format uintmax_t values.
(usage): Add -H, --si.
(main): Adjust to renamed option variables.
Use -H if BLOCKSIZE is SI. Add -H.
("human.h"): Include.
(input_blocksize, output_blocksize, conversion_blocksize):
Now size_t instead of long. 0 means unset.
(skip_records, seek_record, max_records): Now uintmax_t, not long.
(w_partial, w_full, r_partial, r_full, r_truncate):
Now uintmax_t instead of unsigned.
(print_stats): Print counts as uintmax_t, not unsigned.
(main, skip): Check for overflow when computing file offsets.
(skip): Records count arg is uintmax_t, not long; blocksize arg is
size_t, not long. Try lseek even on non regular files, as per comment.
(oc, col): Now size_t, not int.
(copy): No need to check max_records >= 0 any more, as the
default value is now effectively infinity.
Cast lseek arg to off_t.
(copy, copy_with_block): conversion_blocksize - col can never
be negative now, since it's unsigned, so rewrite loops to
avoid problems with unsigned.
(scanargs): Parse numeric args using uintmax_t, not int.
Check for overflow when converting block size args to size_t.
Blocksize options are now unsigned, and are now 0 when not set yet.
(parse_integer): Return uintmax_t, not int; accept new int * arg
to store error indicator, since all returned values are now valid.
Check for overflow when scanning integer.
Include <inttypes.h> if available.
(adjust_blocks, CONVERT_BLOCKS): Remove.
(get_fs_usage): Set new member fsu_blocksize, and do not convert
numbers to 512-byte block units; this avoids overflow here.
Cast lseek arg to off_t, not long.
Avoid arithmetic overflow when size is near max.
Depend on _POSIX_SOURCE and BSIZE, not _POSIX_VERSION, for
compatibility with system.h.
(BSIZE): Remove definition, since if BSIZE is not defined
we're never invoked.
