   5 - explicit blocks with missing end macro should be implicitely closed
   6   at the end of the enclosing block, e.g. .Bl It (El) Sh

   9 - fix bad block nesting involving multiple identical explicit blocks
  10   see the OpenBSD mdoc_macro.c 1.47 commit message
  11
  12 - .Bl -column .Xo support is missing
  13   ultimate goal:
  14   restore .Xr and .Dv to
  15   lib/libc/compat-43/sigvec.3
  16   lib/libc/gen/signal.3
  17   lib/libc/sys/sigaction.2
  18
  19 - implement \\
  20   in plain text, identical to \e
  21   as a macro argument, identical to \ i.e. escaping the next character
  22   We do not have macro definitions yet; if we implement them,
  23   \\ must behave in a macro def like in a macro argument,
  24   and when using the macro, it must expand yet again.
  25
  26 - implement \s (physical font size)
  27   \sN - set to N
  28   \s+N - increment by N, 1 <= N <= 8
  29   \s-N - decrement by N, 1 <= N <= 8
  30   \s0 - restore previous size
  31   \s(nn \s+-(nn \s'+-nn' \s+-'nn' \s[+-nn] \s+-[nn] - disambiguate
  32   registers: .s .ps .sr .psr
  33   used by e.g. cu(1), tip(1)
  34
  35 - look at bsd.lv tbl(1)
  36   from kristaps@  Fri, 11 Sep 2009 17:10:53 +0200
  37   also look at the mail from Thomas Klausner wiz at NetBSD
  38     on Wed, 2 Jun 2010 11:01:29 +0200
  39
  40 - look at pages generated from reStructeredText, e.g. devel/mercurial hg(1)
  41   These are a weird mixture of man(7) and custom autogenerated low-level
  42   roff stuff.  Figure out to what extent we can cope.

  46 - implement blank `Bl -column', such as
  47   .Bl -column
  48   .It foo Ta bar
  49   .El
  50
  51 - explicitly disallow nested `Bl -column', which would clobber internal
  52   flags defined for struct mdoc_macro
  53
  54 - set a meaningful default if no `Bl' list type is assigned
  55
  56 - have a blank `It' head for `Bl -tag' not puke
  57
  58 - ignore horrendous m[] font colouring
  59   reported by J.C. Roberts
  60
  61 - prohibit `Nm' from having non-text HEAD children
  62   (e.g., NetBSD mDNSShared/dns-sd.1)
  63   (mdoc_html.c and mdoc_term.c `Nm' handlers can be slightly simplified)

  66 * formatting issues: ugly output

  68
  69 - outside list context, text following .Sm off
  70   seems to follow without a blank (TERM_NOBLANK reset late?) e.g.
  71         .Sm off
  72         .Xo
  73         .Op Ar bind_address No /
  74         .Ar port
  75         .Xc
  76         .Sm on
  77         or by enclosing
  78   reported by jmc Tue, 13 Apr 2010 08:48:14 +0100
  79
  80 - empty phrases in .Bl column produce too few blanks
  81   try e.g. .Bl -column It Ta Ta

  88 - none reported right now (yet schwarze@ knows of some)

  91 * performance issues
  92 ************************************************************************
  93
  94 Several areas can be cleaned up to make mandoc even faster.  These are
  95
  96 - improve hashing mechanism for macros (quite important: performance)
  97
  98 - improve hashing mechanism for characters (not as important)
