- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Remove trailing whitespace per mdoc lint warning

Disussed with: gavin

Approved by: joel
MFC after: 3 days

Add helpful clarification text. While not strictly necessary, these
few words make this man page much easier to understand without
re-reading prior parts of the man page.

Mark global functions and/or variables in comm(1) static where possible.

This allows compilers and static analyzers to more thorough analysis.

Remove the advertising clause from UCB copyrighted files in usr.bin. This
is in accordance with the information provided at
ftp://ftp.cs.berkeley.edu/pub/4bsd/README.Impt.License.Change

Also add $FreeBSD$ to a few files to keep svn happy.

mdoc: order prologue macros consistently by Dd/Dt/Os

Although groff_mdoc(7) gives another impression, this is the ordering
most widely used and also required by mdocml/mandoc.

Add SIZE_MAX overflow check

Rewrite input processing to not exit with error on the first EILSEQ found
in the input data but fallback to "binary comparison" instead.

POSIX says: "The input files shall be text files", nothing more,
so the text file with illegal sequence is valid input.
BTW, GNU sort does not fails on EILSEQ too.

- Prevent overflowing of the buffer length variable in getline() by
limiting its maximum value.
- Exit if reallocf(3) fails in getline(). Failure was silently
considered as end-of-file.

Don't read the newline character to line buffer because lines are passed
to wcscoll(3). Newline characters could cause incorrect results when
comparing lines.

Also, if an input line didn't contain a newline character, it was
omitted from the output. According to my interpretation, SUSv3 requires
that the newline is always printed.

Add regression tests for the cases. [1]

The input line length limit mentioned on the manual page was removed by
r179374.

Approved by: trasz (mentor)

Similar to changes previously made to src/usr.bin/uniq/uniq.c,
fix truncation of lines at LINE_MAX characters by dynamically
extending line buffers.

Document input line length limit.

Added the EXIT STATUS section where appropriate.

Document the -i option as being a non-standard extension.

Add support for multibyte characters.

Document the fact that comm(1) does not recognize multibyte characters
in its input. Although doing so would require only trivial changes,
it would be incompatible with the ordering used by sort(1), which is the
primary source of comm's input.

ANSIify function definitions to avoid a warning.
Minor constness changes.

Add a History section. comm(1) appeared in V4.

No need to handle '-' explicitly in getopt() loop.

Use `The .Nm utility'

remove __P

Remove leaf node WARNS?=2 (that mainly I added). This should
help the GCC3 transition and CURRENT in general.

Use LC_ALL to pick LC_COLLATE too (for strcoll())

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

Use __FBSDID().

WARNS=2 fixup.

mdoc(7) police: utilize the new .Ex macro.

Include missing header files which define functions for which gcc has
builtins (e.g., exit, strcmp).

Rework diagnostics text
Remove unused #include

mdoc(7) police: use the new features of the Nm macro.

fix the same typo as in uniq

Cosmetique: use standard prototypes scheme
