assertion failure in tclsh(1) reported by deraadt@ via bentley@

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.
Cleanup suggested by jmc@, OK bentley@.

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.

Prefer mandoc.bsd.lv to mdocml.bsd.lv.

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[].

* Do not discard data that lacks a matching layout cell but remains
within the number of columns of the table as a whole.
* Do not insert dummy data rows for any layout row starting with a
horizontal line, but only for layout rows that would discard all
the data on a matching non-empty data row.
* Print horizontal lines specified in the layout even if there is
no matching data cell.
* Improve the logic for extending vertical lines to adjacent rows,
for choosing cross marks versus line segments, and some related details.

This clearly works when .po is called on the top level, but might
not be sophisticated enough if people call .po inside indentation-changing
contexts, but i haven't seen that in manual pages (yet :).
