+- fix bad block nesting involving multiple identical explicit blocks
+ see the OpenBSD mdoc_macro.c 1.47 commit message
+
- .Bl -column .Xo support is missing
ultimate goal:
restore .Xr and .Dv to
lib/libc/gen/signal.3
lib/libc/sys/sigaction.2
-- .Bk / .Ek is broken, e.g.
- $ man ssh
- [...]
- ssh [-1246AaCfgKkMNnqsTtVvXxYy] [-b bind_address] [-c cipher_spec] [-D
- [bind_address:]port] [-e escape_char] [-F configfile] [-I pkcs11]
- reminded by Ludo Smissaert Mon, 10 May 2010 12:15:11 +0200
- also reported by jmc@ earlier
+- edge case: decide how to deal with blk_full bad nesting, e.g.
+ .Sh .Nm .Bk .Nm .Ek .Sh found by jmc@ in ssh-keygen(1)
+ from jmc@ Wed, 14 Jul 2010 18:10:32 +0100
+
+- auto-Bk in the SYNOPSIS
+ patch from kristaps@ Fri, 16 Jul 2010 14:51:24 +0200
+ to be revisited after OpenBSD 4.8 tree unlock
- implement \\
in plain text, identical to \e
\\ must behave in a macro def like in a macro argument,
and when using the macro, it must expand yet again.
-- look at bsd.lv tbl(1)

+- implement basic non-parametric .de to support e.g. sox(1)
+ .de SP
+ .if t .sp .5
+ .if n .sp
+ ..
+ .de EX
+ .SP
+ .nf
+ .ft CW
+ ..
+ .de EE
+ .ft R
+ .SP
+ .fi
+ ..
+ reported by naddy@ Sat, 16 Oct 2010 23:51:57 +0200

+- implement parametric .de to support e.g.
+ /usr/xenocara/lib/libXxf86vm/manXF86VM.man
+ .de ZN
+ .ie t \fB\^\\$1\^\fR\\$2
+ .el \fI\^\\$1\^\fP\\$2
+ ..
+ .ZN -lXxf86vm
+
+- 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
+ or serious mangling of formatting (e.g. \n) -> ERROR
+ see textproc/mgdiff(1) for nice examples
+ (3) undefined, just output the character -> perhaps WARNING
+
+- 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

- implement blank `Bl -column', such as
.Bl -column
.It foo Ta bar
- explicitly disallow nested `Bl -column', which would clobber internal
flags defined for struct mdoc_macro
+- inside `.Bl -column' phrases, punctuation is handled like normal
+ text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
+
+- inside `.Bl -column' phrases, TERMP_IGNDELIM handling by `Pf'
+ is not safe, e.g. `.Bl -column .It Pf a b .' gives "ab."
+ but should give "ab ."
+
- set a meaningful default if no `Bl' list type is assigned
- have a blank `It' head for `Bl -tag' not puke
-
+
+- prohibit `Nm' from having non-text HEAD children
+ (e.g., NetBSD mDNSShared/dns-sd.1)
+ (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)
+
+- allow `Qq', `Dq', `Sq', `Aq', `Bq' to have 0 arguments
+ noted by Alex Kozlov 08/06/10 23:05
+
+- Have `Sh', `It', `Ss' and others complain if `Pp' is invoked prior to
+ close (in the post validation) or prior to open (pre). This noted by
+ jmc@ a thousand years ago.
+
+- xloadimage(1) wants .ti (temporary indent), rep by naddy@
+
+- bashbug(1) complains "line scope broken" after
+ .SM
+ .B something
+ should either just work or be a warning

-- URGENT, this is making many kernel manuals look bad:

- .Sh DIRECT CONFIGURATION
- .nr nS 1
- .Ft "struct device *"
- .Fn config_found_sm "struct device *parent"

+- perl(1) SYNOPSIS looks bad; reported by deraadt@
+ 1) man(7) seems to need SYNOPSIS .Nm blocks, too
+
+- In .Bl -column,
+ .It Em Authentication<tab>Key Length
+ ought to render "Key Length" with emphasis, too,
+ see OpenBSD iked.conf(5).
- empty phrases in .Bl column produce too few blanks
try e.g. .Bl -column It Ta Ta

-- nroff inserts a space before :, mandoc doesn't:
- .Dl expr "/$a" Li : '.*/\e(.*\e)'

************************************************************************
* formatting issues: gratuitious differences
************************************************************************
-- FIXED OpenBSD mdoc.c 1.52 schwarze 16.5.10
- lines containing blank characters, and nothing else,
- in literal context (.Bd -literal):
- groff outputs just blank lines "\n"
- mandoc outputs blanks to the left margin,
- then the number of balnks minus one
- NEEDS MERGING TO bsd.lv
+- .Rv (and probably .Ex) print different text if an `Nm' has been named
+ or not (run a manual without `Nm blah' to see this). I'm not sure
+ that this exists in the wild, but it's still an error.
+- .%T should be quoted, not underlined, when .%J is also present,
+ to better distinguish the contents of .%T and .%J,
+ see for example OpenBSD cat(1)
-************************************************************************
-* parser errors without any effect on formatting
-************************************************************************
+- In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet
+ is just "o\bo".
+ 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).
+
+- .Bd -literal and .Bd -unfilled are *not* identical.
+ In -literal, tabs are 8 spaces.
+ In -unfilled, tabs are 5 spaces, just like in -filled and -ragged.
+ See the CCDF_* display in OpenBSD ccdconfig(8).
+
+- .Nx 1.0a
+ should be "NetBSD 1.0A", not "NetBSD 1.0a",
+ see OpenBSD ccdconfig(8).
+
+- In .Bl -tag, if a tag exceeds the right margin and must be continued
+ on the next line, it must be indented by -width, not width+1;
+ see "rule block|pass" in OpenBSD ifconfig(8).
-- OpenBSD::PackageName(3p) has "if (block) 90:1" in the parse tree
+- 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
+
+- It seems that .TP does not want TWOSPACE after the tag;
+ see bashbug(1); reported by naddy@
+
+- 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
************************************************************************
* performance issues
Several areas can be cleaned up to make mandoc even faster. These are
-- cache `Bd' display types as `Bl' types are cached (this primarily
- improves code-size by removing the a2disp type functions)
-
-- improve caching mechanism to handle other per-element arguments so
- that they need not be recalculated between front- and back-ends (also
- reduces code size and complexity)
-
- improve hashing mechanism for macros (quite important: performance)
- improve hashing mechanism for characters (not as important)
+
+- the PDF file is HUGE: this can be reduced by using relative offsets
