8d68c85340 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.

ba068938d1 Mark global functions and/or variables in comm(1) static where possible. 
This allows compilers and static analyzers to more thorough analysis.

3960614646 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.

a97c77aebb 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.

34aba95524 - 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.

6f2f9130ae 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]

2ec6e3b662 Document the fact that comm(1) does not recognize multibyte characters

it would be incompatible with the ordering used by sort(1), which is the
primary source of comm's input.

d9613ea383 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.
