G. Branden Robinson changed the -T ascii rendering
of \(sd, the "second" symbol, U+2033 DOUBLE PRIME, from '' to ".
Follow suit in mandoc.

escape sequence retains its syntax but usually ignores its argument

character", and "unknown special character" from the generic "invalid
escape sequence", also promoting them from WARNING to ERROR because
incomplete escape sequences are severe syntax violations and because
encountering an invalid or unknown special character makes it likely
that part of the document content intended by the authors gets lost.

1. Move invalid two-byte sequences after valid ones
and make their descriptions easier to understand.
2. Replace the wrong and confusing expression "middle byte"
with the correct term "start byte".
3. Add test lines for U+EFFFF and U+F0000.
4. Replace the unhelpful word "strange" with more descriptive terms.
Arguably, nothing about this (or maybe everything?) is strange.

The test uses U+07FF NKO TAMAN SIGN because it is the highest
code point having a two-byte UTF-8 representation.
This character is a new single-width punctuation character in
Unicode 11, such that mandoc now does correct horizontal spacing.
We already used the code point for the test before it was assigned,
which resulted in weird spacing because wcwidth(3) returns -1 for
unassigned code points.

by the <p> HTML element and use the html_fillmode() mechanism
for .Bd -unfilled, just like it was done for man(7) earlier, finally
getting rid both of the horrible <div class="Pp"></div> hack and
of the worst HTML syntax violations caused by nested displays.
Care is needed because in some situations, paragraphs have to remain
open across several subsequent macros, whereas in other situations,
they must get closed together with a block containing them.
Some implementation details include:
* Always close paragraphs before emitting HTML flow content.
* Let html_close_paragraph() also close <pre> for extra safety.
* Drop the old, now unused function print_paragraph().
* Minor adjustments in the top-level man(7) node formatter for symmetry.
* Bugfix: .Ss heads suspend no-fill mode, even though .Ss doesn't end it.
* Bugfix: give up on .Op semantic markup for now, see the comment.

When after a \\, \t, or \a, another \t or \a had to be resolved
in copy mode within the same argument, the argument got corrupted.

* Add the missing special character \_ (underscore).
* Partial implementations of \a (leader character)
and \E (uninterpreted escape character).
* Parse and ignore \r (reverse line feed).
* Add a WARNING message about undefined escape sequences.
* Add an UNSUPP message about unsupported escape sequences.
* Mark \! and \? (transparent throughput)
and \O (suppress output) as unsupported.
* Treat the various variants of zero-width spaces as one-byte escape
sequences rather than as special characters, to avoid defining bogus
forms with square brackets.
* For special characters with one-byte names, do not define bogus
forms with square brackets, except for \[-], which is valid.
* In the form with square brackets, undefined special characters do not
fall back to printing the name verbatim, not even for one-byte names.
* Starting a special character name with a blank is an error.
* Undefined escape sequences never abort formatting of the input
string, not even in HTML output mode.
* Document the newly handled escapes, and a few that were missing.
* Regression tests for most of the above.

causes horrible churn anyway, profit of the opportunity to stop
excessive testing, such that this is hopefully the last instance
of such churn. Consistently use OpenBSD RCS tags, blank .Os,
blank fourth .TH argument, and Mdocdate like everywhere else.
Use -Ios=OpenBSD for platform-independent predictable output.

native C libraries of illumos, Oracle Solaris 11, and SunOS 5.10.
While it is useful to catch wcwidth(3) regressions on OpenBSD, the
purpose of the *portable* mandoc regression suite is not to check
the C library of the host system; that would just hide genuine
mandoc portability issues in the noise. The remaining UTF-8 tests
are still sufficient to establish that mandoc does the right thing.
