- the roff parser doesn't tolerate additional characters between
a macro and the \} terminating a conditional block, e.g.
.if n \{
.br \}

- in literal mode, the man(7) -Tascii formatter
breaks the line between macro arguments,
e.g. ".B #include <libintl.h>" in gettext(3)

- pod2man expects `tr' to be implemented for \*(-- to work
- implement `rm' - it is easy to do and used in the pod2man preamble

- 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/compat-43/sigvec.3
lib/libc/gen/signal.3
lib/libc/sys/sigaction.2
- 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)

- \\ is now implemented correctly
* when defining strings and macros using .ds and .de
* when parsing roff(7) and man(7) macro arguments
It does not yet work in mdoc(7) macro arguments
because libmdoc does not yet use mandoc_getarg().
Also check what happens in plain text, it must be identical to \e.
- implement basic non-parametric .de to support e.g. sox(1)
reported by naddy@ Sat, 16 Oct 2010 23:51:57 +0200
*** sox(1) still doesn't work, tbl(1) errors need investigation
- 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
- 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.

- implement blank `Bl -column', such as
.Bl -column
.It foo Ta bar
.El
- 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)
- 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

- double quotes inside double quotes are escaped by doubling them
implement this in mdoc(7), too
so far, we only have it in roff(7) and man(7)

- 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

- in enclosures, mandoc sometimes fancies a bogus end of sentence

************************************************************************
* formatting issues: gratuitious differences
************************************************************************
- .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.
- 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).
Also have `It' complain if `Pp' is invoked at certain times (not
-compact?).
- .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).
- 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);

- 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

************************************************************************
- .fi without preceding .nf need not be an ERROR,
a warning is sufficient; occurs in all postfix manuals
reported by brad@ Sun, Jan 09, 2011 at 09:45:58PM -0500
- downgrade "ERROR: macro requires body argument(s)" to WARNING
for the typical man(7) cases, it keeps confusing people

************************************************************************
* performance issues
************************************************************************
Several areas can be cleaned up to make mandoc even faster. These are
- 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
************************************************************************
* structural issues
************************************************************************
- Find better ways to prevent endless loops
in roff(7) macro and string expansion.
