once, print "(N times)" after the message "referenced manual not
found", to lessen the risk that people fix the first instance and
miss the others; jmc@ confirmed that this is useful.

looking in the current working directory. Not a security issue
because the files are never open(2)ed, only access(2)ed.
Requested by jmc@ and inspired by mdoclint(1).
This cannot be perfect because it only works for files having the
exact filename ./pagename.sec - mandoc has no way to figure out
which files might contain a manual for multiple names, or that files
in autohell might be called ./pagename.man.in instead, or which
subdirectories might contain additional source files. Also, it may
hide messages if you have bogus stuff lying around in the directory
where you run mandoc -Tlint. But jmc@ considers it important, and
good enough for everyday use.
Also avoid leaking the memory for the file name while here.

fall back from database search to file system search
just like man(1) does when looking up manuals.
This is not too expensive because on a system having up-to-date
mandoc.db(5) files, it only prolongs the time needed to check
*invalid* references - and you are not supposed to have many of
those, right? And on a system with missing or invalid mandoc.db(5)
files, spending a bit of time and warning loudly about the real
problem is also better than quickly issuing bogus warnings about
cross references that are actually valid.

in the base system, inspired by mdoclint(1).
We are able to do this because (1) the -mdoc parser, the -Tlint validator,
and the man(1) manual page lookup code are all in the same program
and (2) the mandoc.db(5) database format allows fast lookup.
Feedback from, previous versions tested by, and OK jmc@.
A few features will be added to this in the tree, step by step.

Remove several lies, lots of duplicate information,
and a lengthy discussion of features we don't support.
Clarify the wording in some places and make it more concise in others.
Delete examples from where they don't belong
and write a new EXAMPLES section from scratch.

modes instead of four functions, resulting in considerable
simplification, fifty lines less of code, fifteen fewer automatic
variables, and several bug fixes, for example:
1. The delim control statement consumes exactly two bytes of input,
requires no whitespace after these two bytes, and does not treat
quotes in any special way.
2. If the argument of left, right, gfont, gsize, or size is defined
as an alias, only the first word of the value is used as the
delimiter, font name, or font size.
3. If a back, fwd, down, or up keyword is followed by another keyword
instead of the required number, GNU eqn does nothing useful, but
typically errors out. So no need to have special handling (with
an ugly goto!) for it in mandoc.
Also getting rid of one pointless static buffer and twelve redundant
calls to strlcpy(3).

I'm using a very simple, linear time / zero space fuzzy string
matching heuristic rather than a full Levenshtein metric, to keep
the code both simple and fast.

-Wopenbsd and -Wnetbsd to check conventions for the base system of
a specific operating system. Mark operating system specific messages
with "(OpenBSD)" at the end.
Please use just "-Tlint" to check base system manuals (defaulting
to -Wall, which is now -Wbase), but prefer "-Tlint -Wstyle" for the
manuals of portable software projects you maintain that are not
part of OpenBSD base, to avoid bogus recommendations about base
system conventions that do not apply.
Issue originally reported by semarie@, solution using
an idea from tedu@, discussed with jmc@ and jca@.

It is an OpenBSD addition that did not get used a single time in
three years, and groff did not pick it up either, so removing it
does not affect any existing manuals anywhere.

not as letters, even if their names contain letters.
This is certainly not perfect, but code to recognize that \(*a is
not an operator but a letter would need a huge table, or Unicode
character property support, which won't happen at this time.

1. Inherit the font attribute from the parent box, such that iteration
is no longer required to find the current font.
2. For well-known function name tokens, do not insert an EQN_LISTONE
box into the AST; simply set the font attribute of the text box
itself that contains the name.
Also improve word splitting of unquoted strings in default font mode:
3. Split between numbers and punctuation because both will soon get
different HTML markup.
4. Do not split between letters. With the newly ubiquitious font
attributes, all formatters will be able to figure out what to do
without putting each letter into a separate box.

Issue reported by bentley@.
The AST data structure is powerful enough that all required
information can easily be provided in the parser, and no change
of the formatting code is needed.

The formatters need this to correctly select fonts.

With roff_getstrn(), provide finer control which definitions
can be used for what:
* All definitions can be used for .if d tests and .am appending.
* User-defined for \* expansion, .dei expansion, and macro calling.
* Predefined for \* expansion.
* Standard macros, original or renamed, for macro calling.
Several related improvements while here:
* Do not return string table entries that have explicitly been removed.
* Do not create a rentab entry when trying to rename a non-existent macro.
* Clear an existing rentab entry when the external interface
roff_setstr() is called with its name.
* Avoid trailing blanks in macro lines generated from renamed
and from aliased macros.
* Delete the duplicate __m*_reserved[] tables, just use roff_name[].
