2. Do not keep a list of equation parsers, one parser is enough.

Simplify by just using EQN_LIST with expectargs = 1.

* Make enum rofft an internal interface as enum roff_tok in "roff.h".
* Represent mdoc and man macros in enum roff_tok.
* Make TOKEN_NONE a proper enum value and use it throughout.
* Put the prologue macros first in the macro tables.
* Unify mdoc_macroname[] and man_macroname[] into roff_name[].

Use them to mark generated nodes and nodes that shall not produce output.
Let -Ttree output mode display these new flags.
Use NODE_NOSRC for .Ar, .Mt, and .Pa default arguments.
Use NODE_NOPRT for .Dd, .Dt, and .Os.
These will help to make handling of text production macros more rigorous.

that were right between two adjacent case statement. Keep only
those 24 where the first case actually executes some code before
falling through to the next case.

man_node() from the mandoc(3) semi-public interface and the internal

Replace struct mdoc_node and struct man_node by a unified struct roff_node.
To be able to use the tok member for both mdoc(7) and man(7) without
defining all the macros in roff.h, sacrifice a tiny bit of type safety
and make tok an int rather than an enum.
Almost mechanical, no functional change.

* Print mnemonics, not code numbers for expression positions.

This adds parser-level support for the grammar described by the eqn
second-edition technical paper, "Typesetting Mathematics — User's Guide"
(Kernighan, Cherry).
The reason for this re-write is the grouping rules, which were not
possible given the existing implementation.
The re-write has also considerably simplified the HTML (and, if it ever
is completed, terminal) front-end.

Include <sys/types.h> where needed, it does not belong in config.h.
Remove <stdio.h> from config.h; if it is missing somewhere, it should
be added, but i cannot find a *.c file where it is missing.

use the MAN_LINE flag instead of the man_node line member.
This is required such that user-defined macros wrapping .TP work correctly.

the NetBSD bug tracking system and Thomas Klausner <wiz at NetBSD>.

we have to compare the line where the first one *ends* (not where it begins)
to the line where the second one starts.
This fixes the bug that .Bk allowed output line breaks right after block
macros spanning more than one input line, even when the next macro follows
on the same line.

whether they are the first macro on the line or called by another macro.
To help debugging, indicate this property "first macro on a new input line"
by prefixing an asterisk to the line number in -Ttree output.

along with the dead code testing whether it's positive.
Reported by Ulrich Spoerlein <uqs@spoerlein.net>,
found by Coverity Scan CID 975717.
While here, remove the now unused **params array as well,
which Coverity apparently missed, at least it wasn't reported...

CACM paper in an LR(1) parse (1 -> eqn_rewind()). Right now the code is
a little jungly, but will clear up as I consolidate parse components.
The AST structure will also be cleaned up, as right now it's pretty ad
hoc (this won't change the parse itself). I added the mandoc_strndup()
function will here.

always hold, which cleans up the table stuff a bit.
Second, set a "spans" value per data cell consisting of the number of
skipped TBL_CELL_SPAN layout cells.
Third, make tbl_term.c understand how to skip over spanned sections when
iterating over the header queue.
What remains is to calculate the widths of spanned cells.

for front-ends to make decisions about widths, not the back-end.
To pull this off, first make each tbl_head contain a unique index value
(0 <= index < total tbl_head elements) and remove the tbl_calc() routine
from the back-end.
Then, when encountering the first tbl_span in the front-end, dynamically
create an array of configurations (termp_tbl) keyed on each tbl_head's
unique index value. Construct the decimals and widths at this time,
then continue parsing as before.
The termp_tbl and indexes are required because we pass a const tbl AST
into the front-end.
