validity of character escape names and warn about unknown ones.
This requires mchars_spec2cp() to report unknown names again.
Fortunately, that doesn't require changing the calling code because
according to groff, invalid character escapes should not produce
output anyway, and now that we warn about them, that's fine.

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.

This is good because <p> is brittle: it can't appear within other block
macros.
This fixes a regression of the original HTML5 patch as noted by schwarze@
on the tech@ list, 14/8/2014.

This uses a <style /> block right before the <link /> for the stylesheet.
Use this to kick out hardcoded header and footer table widths.

The .Bf block can contain subblocks, so it has to render as an
element that can contain flow content. But <em> cannot contain
flow content, only phrasing content. Rendering .Em and .Bf differently
would by unfortunate, and closing out .Bf before subblocks and
re-opening it afterwards would merely complicate both the C code
of the program and the generated HTML code. Besides, converting
.Em to semantic HTML markup would require some content to be put
into <em> and some into <i>, but we cannot automatically distinguish
which is which, so strictly speaking, we can't use semantic HTML
here but have to fall back to physical markup. Wonders of HTML...

The vast majority of .Em in real-world manuals is stress emphasis,
for which <em> is the correct markup. Admittedly, there are some
instances of .Em usage for alternate quality, for which <i> would
be a better match. Most of these are technical terms that neither
allow semantic markup nor are keywords - for the latter, .Sy would
be preferable. A typical example is that the shell breaks input into
.Em words .
Alternate voice or mood, which would also require <i>, is almost
absent from manuals.
We cannot satisfy both stress emphasis and alternate quality, so
pick the one that fits more often and looks less wrong when off.

Fix one case where a non-literal is used as format string.
Fix another case where a variable is formatted using the wrong type.
|

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

character without advancing the cursor position; implement it to
simply skip the next character, as it will usually be overwritten.
With this change, the pod2man(1) preamble user-defined string \*:,
intended to render as a diaeresis or umlaut diacritic above the
preceding character, is rendered in a slightly less ugly way,
though still not correctly. It was rendered as "z.." and is now
rendered as ".".
Given that the definition of \*: uses elaborate manual \h positioning,
there is little chance for mandoc(1) to ever render it correctly,
but at least we can refrain from printing out a spurious "z", and
we can make the \z do something semi-reasonable for easier cases.

have bufcat() simply call through to strlcat(). Finally, assert()

Also rename buffmt() -> bufcat_fmt() to differentiate from buffmt_man et

change any code but for renaming functions and types to be consistent
with other mandoc.h stuff. The reason for moving into libmandoc is that
the rendering of special characters is part of mandoc itself---not an
external part. From mandoc(1)'s perspective, this changes nothing, but
for other utilities, it's important to have these part of libmandoc.
Note this isn't documented [yet] in mandoc.3 because there are some
parts I'd like to change around beforehand.

set by COL, until an external macro is encountered. At this point in
time, close out the table and process the macro. When the first table
row is again re-encountered, re-start the table. This requires a bit of
tracking added to "struct html", but the change is very small and
follows the logic of meta-fonts. This all follows a bug-report by
joerg@.

using \fI or \fP). Now, using these modes will cause a font to be
rendered for each word; furthermore, setting mode within a word will do
the correct thing.
Second, make -man use real font tags (B, I, SMALL) to set its font
instead of using font modes and fix up the pre-macro unsetting of the
current mode.
This fixes how roff.7 wasn't validating (<P> closing out a font mode)
and has been checked against gcc.1 (more will come). I considered
failure to validate OUR manual to be a show-stopper for the up-coming
release.
