\\ must behave in a macro def like in a macro argument,

and when using the macro, it must expand yet again.

- port OpenBSD tbl integration bsd.lv, probably cleaning it up

- 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.

to better distinguish the contents of .%T and .%J,

see for example OpenBSD cat(1)

- .It ${name Ns [ selector ] Ns }

should be "${name[selector]}" not "${name [selector]}"

This is parsed as

text("${name") text("[") Ns() text(selector)...

Opening punctuation should not fall out of .Ns.

see for example OpenBSD csh(1)

- .%A should append the last author with " and " (if there are two)

or ", and " (if there are more), not ", "

see for example OpenBSD csh(1)

- In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet

is just "o\bo".

see for example OpenBSD ksh(1)

- .No text No ) is "text )", not "text)"

see the terrible example

case word in [[(] pattern [| pattern] ... ) list ;; ] ... esac

in OpenBSD ksh(1)

- .Sm should *not* produce as a blank line in .Bd -literal

see for example "Brace expansion" in 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"

Line 140

Line 149

In -unfilled, tabs are 5 spaces, just like in -filled and -ragged.

See the CCDF_* display in OpenBSD ccdconfig(8).

- In .Bd -unfilled, .Pp should produce one blank line, not two;

see the ccd.conf display in OpenBSD ccdconfig(8).

- .Nx 1.0a

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

see OpenBSD ccdconfig(8).

Line 151

Line 157

on the next line, it must be indented by -width, not width+1;

see "rule block|pass" in OpenBSD ifconfig(8).

- When .%T is used outside an .Rs context and with a trailing comma,

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

there is no point in rendering two commata,

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

see the first paragraph of the DESCRIPTION in OpenBSD mount_nfs(8).

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

- When .%T is used outside an .Rs context and without a trailing comma,

no comma should be rendered at all,

see the first paragraph of the DESCRIPTION in OpenBSD exports(5).

- Bogus .Pp before .Bl should not cause a double blank line,

see "The route utility provides the following simple commands:"

in OpenBSD route(8).

- rendering frontend code can calculate widths only for plain strings,

not for strings containing escape sequences. For example, this

hinders calculation of the indent required for .Nm \&[ in text(1).

comments from kristaps@ Wed, 21 Jul 2010 23:26:08 +0200

- another example of the same problem:

.Bl -tag -width "\eD{format}XX" -compact

in OpenBSD ksh(1) gives the wrong width

because "\e" is one character in groff, two in mandoc

- Now that `ds' is minimally supported, we can get rid of some

predefined strings. \*(C+ has already been thrown out. Track these

down and whack them. Look in e.g. gcc.1 for the top-level `ds'

invocations. These are reproduced across most crappy GNU manuals.
