and link names if necessary.
(tar-header-block-summarize): Handle the case that file or link
names are multibyte.
(tar-summarize-buffer): At first set the current buffer unibyte,
then if there are multibyte file names, change it to multibyte.
(tar-mode): Get char position from tar-header-offset.
(tar-extract): Avoid multibyte<->unibyte conversion in
insert-buffer-subsring by setting both buffers unibyte
temporarily.
(tar-copy): Set the buffer unibyte while doing a work. Write
without code conversion.
(tar-expunge): Set the buffer unibyte while doing a work.
(tar-alter-one-field): Likewise.
(tar-clear-modification-flags): Compare byte position with
tar-header-offset.
(tar-subfile-save-buffer): Avoid multibyte<->unibyte conversion in
insert-buffer-subsring by setting both buffers unibyte
temporarily. Pay attention to multibyteness while updating the
descriptor-line.
(tar-mode-write-file): Write without code conversion.
(tar-extract): Detect coding-system of the archive member and
decode it like insert-file-contents does.
(tar-alter-one-field): Reposition point on the file name of the
current tar entry.
(tar-subfile-save-buffer): Encode the file when updating it in the
archive, and use the size of encoded text to update the header
block. Set last-coding-system-used to coding-system of the file.
Restore point of tar-superior-buffer after updating the descriptor line.
(tar-subfile-mode): Doc fix.
(tar-expunge): Make questions and messages start with upper case letter.
(tar-summarize-buffer): Ditto.
(tar-subfile-save-buffer): Make message like others.
(tar-mode): Locally bind local-write-file-hooks.
(tar-mode-write-file): Renamed from tar-mode-maybe-write-tar-file.
(tar-mode-write-file): Simplify to only work for tar file buffers.
(write-file-hooks): Don't modify this.
current-time compatible a list of 16-bit ints (HIGH LOW).
(tar-parse-octal-integer): Write char-const '0' as
?0 instead of more obscure 48.
(tar-parse-octal-long-integer): New function.
(tar-clip-time-string): New function.
(tar-header-block-summarize, tar-header-block-summarize):
Insert mod-time into listing.
(tar-next-line): Move goal column to new location of filenames.
(tar-mode-show-date): New variable.
(tar-header-block-summarize, tar-next-line): Obey it.
set-visited-file-name.
Various renamings; all callers changed.
(tar-header-block-tokenize): Renamed from tokenize-tar-header-block.
(tar-header-block-checksum): Renamed from checksum-tar-header-block.
(tar-header-block-check-checksum):
Renamed from check-tar-header-block-checksum.
(tar-header-block-recompute-checksum):
Renamed from recompute-tar-header-block-checksum.
(tar-header-block-summarize):
Renamed from summarize-tar-header-block.
