cut(1): implement the -n option (for use with -b)

This command had long advertised the existence of -n (in its usage
message and man page) but had never implemented it. Here we borrow the
implementation written by Tim J. Robbins for FreeBSD, which provides
most code changes and almost all documentation changes applied here. We
also borrow some options handling simplifications from OpenBSD, with
some minor tweaks to code and documentation by me.

Addresses PR bin/59029. This is a pretty obscure feature, it seems, so
it's unlikely it will be pulled up to stable branches.

cut.1:
- bump date;
- synchronize argument name to `-d' (prefer ``string'' above
``delim'' since it's not just a single character that can be
given (even though only one, being the first one, is actually
used));
- improve wording;
- use macro for `EXIT STATUS' section.

cut.c: simplify a comment

From a commit by Tim J. Robbins to FreeBSD back in 2004:
"Update a comment that compared the parser with an obsolete draft of
IEEE Std 1003.2-1992. Most of the "extensions" here were actually
required by the final version of the standard."

message and man page) but had never implemented it. Here we borrow the

From Igor Sobrado in private email (based on his OpenBSD commit):

improve POSIX compliance by continuing to process the remaining file
operands after not finding an input file.

from the IEEE Std 1003.1-2008 (``POSIX.1'') rationale:

"Unlike other utilities, some historical implementations of cut
exit after not finding an input file, rather than continuing to
process the remaining file operands. This behavior is prohibited
by this volume of POSIX.1-2008, where only the exit status is
affected by this problem."

Teach 'cut -c' about multibyte characters. Fixes PR 34244,
using the patch from the PR and some hacking by myself to avoid code
redundancy.

Passes the regression tests I've added.

(How many weeks of purgatory do I get for the cpp(1) hack to avoid
code redundancy? I guess I can always say it was inspired by some old
version of our md5 sources...)

PR/33995: Aleksey Cheusov: support use "-" to indicate stdin from SUS

Coverity CID 2790: Always free tmp buffer, not somethimes.

If fgetln() returns a buffer that isn't terminated by \n, free the temporary
buffer inside the loop. Fixes coverty CID:1674.
(This should only happen at EOF, so the loop SHOULD terminate.)
While here always output a newline at the end of the input data even when
the last (unterminated) line doesn't contain a separator.

a fix from openbsd.
XXX is it better to output a newline?
