A full implementation would require access to output device properties
and state variables (both only available after the main parser has
finalized the parse tree) before numerical expansions in the roff
preprocessor (i.e., before the main parser is even started).
Not trying to pull that stunt right now because the static-width
implementation committed here is sufficient for tcl-style manual pages
and already more complicated than i would have suspected.

Good enough to cope with the average DocBook insanity.

If is not a macro but a low-level roff request
and not recommended for use in manual pages.

Actually using these is very stupid because they are groff extensions
and other roff(7) implementations typically print unintended characters
at the places where they are used.
Nevertheless, some manuals contain them, for example ocserv(8).

This is another missing feature required for ocserv(8).

implementation. As a side effect, minus ten lines of code.
As another side effect, this also fixes the assertion failure that
used to be triggered by "\z\o'ab'c" at the beginning of an output
line, found by jsg@ with afl (test case 022/Apr27).

For .it, ignore scaling units in roff_getnum().
Inside parentheses, skip whitespace after a sign in roff_getnum().
Parse and ignore unary plus in roff_getnum().
As a bonus, get rid of the only call to mandoc_strntoi() in roff.c.

Remove lots of lies, dozens of irrelevant implementation details,
and all references to groff versions older than 1.17. Move relevant
information to the pages where it belongs, and out of mandoc(1) in
particular. Add some missing general remarks to roff(7), where it
fits the character and purpose of the page much better.

is sometimes harmless, it often causes seriously ugly output,
so flag these requests as unsupported rather than ignoring them.
Discussed with naddy@.

scaling units, and some manuals (e.g. in devel/grcs) actually use that,
so let's support it. Missing feature reported by naddy@.

This is of some relevance because the pod2man(1) preamble abuses it
for the icelandic letter Thorn, instead of simply using \(TP and \(Tp.

using mandoc is better than using groff) and -Wunsupp (manual using
unsupported low-level roff(7) feature, probably using groff is better
than using mandoc). Once this feature is complete, it is intended
to help porting, making the decision whether to USE_GROFF easier.
As a first step, distinguish four classes of roff(7) requests:
1. Supported (currently 24 requests)
2. Currently ignored because unimportant (120) -> no message
3. Ignored for good because insecure (14) -> -Werror
4. Currently unsupported (68) -> these trigger the new -Wunsupp messages

for groff compatibility because pod2man(1) uses it that way.
Weirdly, groff documents it as "for compatibility with other
troff versions" but neither Heirloom nor Plan 9 have it.

Start with the horizontal terminal specifiers, making sure that they match
up with troff.
Then move on to PS, PDF, and HTML, noting that we stick to the terminal
default width for "u".
Lastly, fix some completely-wrong documentation and note that we diverge
from troff w/r/t "u".

partially implement the \w (measure text width) escape sequence
in a way that makes them usable in numerical expressions and in
conditional requests, similar to how \n (interpolate number register)
and \* (expand user-defined string) are implemented.
This lets mandoc(1) handle the baroque low-level roff code
found at the beginning of the ggrep(1) manual.
Thanks to pascal@ for the report.

Support all binary operators except ';' (scale conversion).
Fully support chained operations and nested parentheses.
Use this for the .nr, .if, and .ie requests.
While here, fix parsing of integer numbers in roff_getnum().

As reported by sthen@, the perl-5.18 pod2man(1) preamble
thinks cool kids use that in manuals. I hope *you* know better.

* Support string comparisons.
* Support negation not only for numerical, but for all conditions.
* Switch the `o' condition from false to true.
* Handle the `c', `d', and `r' conditions as false for now.
* Use int for boolean data instead of rolling our own "enum roffrule";
needed such that we can use the standard ! and == operators.
Havard Eidnes reported via the NetBSD bug tracking system that some
Tcl*(3) manuals need this, and Thomas Klausner <wiz at NetBSD>
forwarded the report to me. This doesn't make the crazy Tcl*(3)
macrology maze happy yet, but brings us a bit closer.

Requests and escape sequences. Consequently, supplement the
REQUEST REFERENCE by an ESCAPE SEQUENCE REFERENCE, such that people
no longer need to guess or experiment what mandoc(1) implements,
what it parses and ignores, and what it doesn't handle at all.

the first non-digit character. While here, implement and document
an optional sign, requesting increment or decrement, as documented
in the Ossanna/Kernighan/Ritter troff manual and supported by groff.

we don't do hyphenation anyway, so there is no point in throwing an ERROR

This improves the formatting of about 40 base manuals
and reduces groff-mandoc formatting differences in base by about 5%.

This was reported by espie@ and in the TODO.
Caveat: `cc' has buggy behaviour when invoked in groff(1) and followed
by a line-breaking control character macro, e.g., in a -man doc,
.cc |
.B foo
'B foo
|cc
'B foo
will cause groff(1) to behave properly for `.B' but inline the macro
definition for `B' when invoked with the line-breaking macro.

1) Move the LANGUAGE SYNTAX from mdoc(7) and man(7) to roff(7),
it's common to both and it's actually roff syntax.
2) Move the MACRO SYNTAX down to the bottom, such that the less
technical parts MANUAL STRUCTURE and MACRO OVERVIEW get to the top.
Getting everything to again fit together after the reshuffling
required various adjustments; also adjust and improve
the DESCRIPTIONS while there.
feedback and "go ahead" jmc@ kristaps@
