Some mildly broken real-world packages on some operating systems
contain dangling symlinks in manual page directories: pestering the
user to run makewhatis(8) makes no sense because that won't help.
On the other hand, missing read permissions deserve ugly error messages
and are unlikely to occur in practice anyway.

try harder to find the best match.
Use this order of preference:
1. The section in both the directory name and the file name matches exactly.
2. The section in the file name matches exactly.
3. The section in the directory name matches exactly.
4. Neither of them matches exactly.
The latter can happen when mansearch() finds substring matches
or when the second .Dt argument mismatches the dir and file names.
Lorenzo Beretta <loreb at github> reported that this caused real
problems on Void Linux, like "man 3 readline" showing readline(3m).
See https://github.com/void-linux/void-packages/issues/9868 for details.

prefer file name matches over .Dt/.TH matches over first NAME matches
over later NAME matches, but do not change the ordering for apropos(1)
nor for man -a.
This reverts main.c rev. 1.310 and mansearch.h rev. 1.29
and includes a partial revert of mansearch.c rev. 1.79.

about the architecture rather than about the manual page name:
$ man -S vax cpu
man: Unknown architecture "vax".
$ man -S sparc64 foobar
man: No entry for foobar in the manual.

1. Fully support no-fill mode in mdoc(7), even when invoked with
low-level roff(7) .nf requests. As a side effect, this substantially
simplifies the implementation of .Bd -unfilled and .Bd -literal.
2. Let .Bd -centered fill its text, using the new TERMP_CENTER flag.
That finally fixes the long-standing bug that it used to operate in
no-fill mode, which was known to be wrong for at least five years.
This also simplifies the implementation of .Bd -centered considerably.

* 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.

horizontal spans, by implementing a moderately difficult iterative
algoritm. The benefit is that spans containing long text no longer
cause an excessive width of their starting column.
The result is likely not optimal, in particular in the presence
of many spans overlapping in complicated ways nor when spans
interact with equalizing or maximizing colums. But i doubt the
practical usefulness of making this more complicated.
Issue originally reported in synaptics(4), which now looks better,
by tedu@ three years ago, and reminded by Pali Rohar this summer.

box drawing characters, U+2500 to U+257F.
Originally suggested by bentley@ four years ago,
reminded this summer by Pali Rohar.
Binary and decimal arithmetics are boring,
so let's use some ternary arithmetics for a change.
That said, some other aspects are too complicated for my liking,
so this could use some polishing in the future.

span cells horizontally and vertically as requested by the layout.
Does not handle spans requested in the data section yet.
To be able to do this, record the number of rows spanned
in the first data cell (struct tbl_dat) of a vertical span.

Needed for example by groff_hdtbl(7).
There are two limitations:
It does not support nested .while requests yet,
and each .while loop must start and end in the same scope.
The roff_parseln() return codes are now more flexible
and allow OR'ing options.

for example used by groff_hdtbl(7) and groff_mom(7).
Also correctly interpolate arguments during nested macro execution
even after .shift and .return, implemented using a stack of argument
arrays.
Note that only read.c, but not roff.c can detect the end of a macro
execution, and the existence of .shift implies that arguments cannot
be interpolated up front, so unfortunately, this includes a partial
revert of roff.c rev. 1.337, moving argument interpolation back into
the function roff_res().

roff conditional, except that the .char request still isn't supported
and that behaviour differs from groff in many edge cases.
But at least valid character names and numbers are now distinguished
from invalid ones.
This also fixes the bug that parsing of the 'c' conditional was
incomplete, which resulted in leaking the tested character to the
input parser at the beginning of the body when the condition was
inverted.

escape sequences, used for example in the groff_char(7) manual page
|

and some groff manual pages actually use them in .ft requests.
It's easy enough to handle these .ft requests in mandoc, too.

Examples of manual pages (ab)using it
include groff(7), chem(1), groff_mom(7), and groff_hdtbl(7).
