34b7df97a3 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.

8d34a0b7bc Mark global functions and/or variables in comm(1) static where possible. 
This allows compilers and static analyzers to more thorough analysis.

aa12cea2cc 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.

8f82dfe5d1 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.

e8861840c8 - 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.

d8eba599f5 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]

831056382b 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.

9f5b04e925 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.
