When -n l/N is used and long lines are present that both
span partitions and multiple buffers, one would get
inconsistent chunk sizes.
* src/split.c (main): Add a new undocumented ---io-blksize option
to support full testing with varied buffer sizes.
(cwrite): Refactor most handling of --elide-empty to here.
(bytes_split): Remove handling of --elide-empty.
(lines_chunk_split): Likewise. The specific issue here
was the first handling of elide_empty_files interfered
with the replenishing of the input buffer.
* test/misc/split-lchunk: Add -e and the new ---io-blksize
combinations to the test.
* src/split.c (usage, long_options, main): New options --number,
--unbuffered, --elide-empty-files.
(set_suffix_length): New function to auto increase suffix length
to handle a specified number of files.
(create): New function. Refactored from cwrite() and ofile_open().
(bytes_split): Add max_files argument to support byte chunking.
(lines_chunk_split): New function. Split file into chunks of lines.
(bytes_chunk_extract): New function. Extract a chunk of file.
(of_info): New struct. Used by functions lines_rr and ofile_open
to keep track of file descriptors associated with output files.
(ofile_open): New function. Shuffle file descriptors when there
are more output files than available file descriptors.
(lines_rr): New function to distribute lines round-robin to files.
(chunk_parse): New function. Parses K/N syntax.
* tests/misc/split-bchunk: New test for byte chunking.
* tests/misc/split-lchunk: New test for line delimited chunking.
* tests/misc/split-rchunk: New test for round-robin chunking.
* tests/Makefile.am: Reference new tests.
* tests/misc/split-fail: Add failure scenarios for new options.
* tests/misc/split-l: Fix a typo. s/ln/split/.
* doc/coreutils.texi (split invocation): Document --number.
* NEWS: Mention the new feature.
* .mailmap: Map new email address for shortlog.

The bug was introduced with commit 23f6d41f, 19-02-2003.
* src/split.c (bytes_split, lines_split, line_bytes_split):
Correctly check the return from full_read().
* tests/misc/split-fail: Ensure split fails when
it can't read its input.
* NEWS: Mention the fix.
* src/system.h: Rename emit_bug_reporting_address() to
emit_ancillary_info() and update it to not print the translation
project address in en_* locales, and _do_ print it in the 'C'
(and other) locales so that it's included in the default man page.
Also mention how to invoke the texinfo documentation for each command.
Also move the "hard-locale.h" include to the 8 files that now use it.
* man/help2man: Strip the newly added texinfo reference from the
--help output as a more verbose version is already added by help2man.
Suggestion from C de-Avillez
* doc/coreutils.texi (multiplierSuffixes): Mention that
the suffix can be specified without a leading number
* src/split.c (usage): Refactor SIZE help to within a function
* src/truncate.c (usage): Likewise
* src/ls.c (usage): Likewise
* src/df.c (usage): Likewise. Also add a function with BLOCKSIZE help
* src/du.c (usage): Likewise.
* src/system.h: Define 2 functions to emit common help text

This is following on from this change:
[02c3dc9d 2008-03-06 cat: use larger buffer sizes ...]
which increased the IO block size used by cat by 8 times,
but also capped it at 32KiB.
* NEWS: Mention the change in behavior.
* src/system.h: Add a new io_blksize() function that
returns the max of ST_BLKSIZE or 32KiB, as this was
seen as a good value for a minimum block size to use
to get good performance while minimizing system call overhead.
* src/cat.c: Use it.
* src/copy.c: ditto
* src/split.c: ditto
* bootstrap.conf (gnulib_modules): Add propername.
(XGETTEXT_OPTIONS): Add options to tell xgettext about the functions.
* src/cat.c, src/cp.c, src/df.c, src/du.c, src/split.c:
Mark Torbjörn Granlund's name.
* src/ptx.c: Mark François Pinard's name.
Use "TRANSLATORS:" comment marker, rather than "Note to translators:".
* src/system.h: Include propername.h.
(proper_name): Define away.
* src/Makefile.am (cat_LDADD, df_LDADD, du_LDADD, ptx_LDADD, split_LDADD):
Initialize, so we can...
(cat_LDADD, cp_LDADD, df_LDADD, du_LDADD, ptx_LDADD, split_LDADD):
...Use "+=" to append $(LIBICONV) for each program that uses
proper_name_utf8.
* src/mkdir.c (verbose_output): New function.
(announce_mkdir): Use it.
* src/split.c (usage): Update.
* src/split.c (cwrite): Write to stdout, not stderr.
* doc/coreutils.texi (split invocation): Remove the mention
of --verbose output being printed to stderr.
* tests/mkdir/p-v: Redirect stdout, not stderr.
* tests/misc/split-a: Likewise.
* NEWS: Mention this change.
* TODO: Remove this item.
suffixes kB, M, MB, G, GB, and so on for T, P, Y, Z, and Y:
head -c, head -n, od -j, od -N, od -S, split -b, split -C,
tail -c, tail -n.
* doc/coreutils.texi (od invocation, head invocation, tail invocation):
Document support for new size suffixes.
(head invocation, tail invocation):
Document that -n uses the same suffixes as -c.
(tail invocation): More-clearly document what leading "+" does.
* src/head.c (usage, string_to_integer): Support new suffixes.
* src/od.c (usage, main): Likewise.
* src/split.c (usage, main): Likewise.
* src/tail.c (usage, parse_options): Likewise.
Prompted by a patch from Evan Hunt.
* src/split.c (line_bytes_split): Don't create an empty line
afterwards if the last buffer happens to be exactly full.
* tests/misc/split-fail: Add a test case for this.
* NEWS: mention this.
Include fd-reopen.h.
(input_desc): Remove. All uses replaced by STDIN_FILENO.
(cwrite): Don't call fd_safer; no longer needed now that
we include fcntl--.h.
(main): Reuse stdin rather than opening a new one. This
saves a file descriptor.
