- ".\}" on its own line gets translated to bare ".\&"

- The abort() in bufcat(), html.c, can be triggered via buffmt_includes()

which forces pset() into man(7)

by running -Thtml -Oincludes on a file containing a long .In argument.

and then triggers an unknown macro error

Fixing this will probably require reworking the whole bufcat() concept.

- tbl(7): Horizontal and vertical lines are formatted badly:

With the box option, there is too much white space at the end of cells.

Horizontal lines from "=" lines are a bit too long.

- The whatis(1) utility looks for whole words in Nm.

If the file name of a page does not agree with the contents of any

of its Nm macros (e.g. pool(9)), add the file name as an Nm entry

to the mandoc.db as well, such that whatis(1) finds it.

If there is a page with a file name that does not appear as a substring

neither in Nm nor in Nd, the same fix would allow finding that page

with apropos(1) using the file name as a key, as well.

Issue reported by tedu@ Fri, 05 Jul 2013 21:15:23 -0400

- makewhatis(8) for preformatted pages:

parse the section number from the header line

and compare to the section number from the directory name

- Does makewhatis(8) detect missing NAME sections, missing names,

and missing descriptions in all the file formats?

- clean up escape sequence handling, creating three classes:

(1) fully implemented, or parsed and ignored without loss of content

(2) unimplemented, potentially causing loss of content

Line 151

Line 182

see textproc/mgdiff(1) for nice examples

(3) undefined, just output the character -> perhaps WARNING

- The \t escape sequence is the same as a literal tab, see for example

the ASCII table in hexdump(1) where

.Bl -column \&000_nu \&001_so \&002_st \&003_et \&004_eo

.It \&000\ nul\t001\ soh\t002\ stx\t003\ etx\t004\ eot\t005\ enq

produces

000 nul 001 soh 002 stx 003 etx 004 eot 005 enq

and the example in oldrdist(1)

- look at pages generated from reStructeredText, e.g. devel/mercurial hg(1)

These are a weird mixture of man(7) and custom autogenerated low-level

roff stuff. Figure out to what extent we can cope.

- perl(1) SYNOPSIS looks bad; reported by deraadt@

Found in mount_nfs(8) and exports(5), search for "Appendix".

- Trailing punctuation after .%T triggers EOS spacing, at least

outside .Rs (eek!). Simply setting ARGSFL_DELIM for .%T is not

the right solution, it sends mandoc into an endless loop.

- formatting /usr/local/man/man1/latex2man.1 with groff and mandoc

reveals lots of bugs both in groff and mandoc...

--- PDF issues ---------------------------------------------------------

- PDF output doesn't use a monospaced font for .Bd -literal

Example: "mandoc -Tpdf afterboot.8 > output.pdf && pdfviewer output.pdf".

Search the text "Routing tables".

Also check what PostScript mode does when fixing this.

see for example OpenBSD ksh(1)

- The characters "|" and "\*(Ba" should never be bold,

not even in the middle of a word, e.g. ".Cm b\*(Bac" in

"mknod [-m mode] name b|c major minor"

in OpenBSD ksh(1)

- A bogus .Pp between two .It must not produce a double blank line,

see between -R and -r in OpenBSD rm(1), before "update" in mount(8),

or in DIAGNOSTICS in init(8), or before "is always true" in ksh(1).

The same happens with .Pp just before .El, see bgpd.conf(5).

Also have `It' complain if `Pp' is invoked at certain times (not

-compact?).

- .Pp between two .It in .Bl -column should produce one,

not two blank lines, see e.g. login.conf(5).

Probably, this should be fixed somewhere in termp_it_pre(), not sure.

- .Nx 1.0a

should be "NetBSD 1.0A", not "NetBSD 1.0a",

see OpenBSD ccdconfig(8).

Line 285

.Bl -tag -width ".Dv message"

in magic(5), located in src/usr.bin/file, is the same

as -width 7n, not -width 11n.

The same applies to .Bl -column column widths;

reported again by Franco Fichtner Fri, 27 Sep 2013 21:02:28 +0200

An easy partial fix would be to just skip the first word if it starts

with a dot, including any following white space, when measuring.

- The \& zero-width character counts as output.

That is, when it is alone on a line between two .Pp,

we want three blank lines, not two as in mandoc.

- When .Fn arguments exceed one output line, all but the first

should be indented, see e.g. rpc(3);

reported by jmc@ on discuss@ Fri, 29 Oct 2010 13:48:33 +0100

- .Ns should work when called at the end of an input line, see

the following code in vi(1):

.It Xo

.Op Ar line

.Cm a Ns Op Cm ppend Ns

.Op Cm !\&

.Xc

The input text is appended after the specified line.

- Header lines of excessive length:

Port OpenBSD man_term.c rev. 1.25 to mdoc_term.c

and document it in mdoc(7) and man(7) COMPATIBILITY

found while talking to Chris Bennett

- In man(7), the sequence

.HP

one line of regular text

.SH

should not produce two blank lines before the .SH,

see for example named-checkconf(8).

- In man(7), the sequence

.SH HEADER

.PP

regular text

should not produce any blank lines between the header and the text,

see for example rsync(1).

Reported by naddy@ Mon, 28 Mar 2011 20:45:42 +0200

- In man(7), the sequence

regular text

.IP

.IP "tag"

indented text

should produce one, not four blank lines between the regular text

and the tag, see for example rsync(1).

Likewise,

regular text

.IP

indented text

should produce one, not two blank lines in between, and

regular text

.IP

.RS

.IP tag

indented text

should produce one, not three blank lines.

Reported by naddy@ Mon, 28 Mar 2011 20:45:42 +0200

- trailing whitespace must be ignored even when followed by a font escape,

see for example
