  ************************************************************************
- - ".\}" 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.

    because libmdoc does not yet use mandoc_getarg().
    Also check what happens in plain text, it must be identical to \e.
+ - .Bd -centered implies -filled, not -unfilled, which is not
+   easy to implement; it requires code similar to .ce, which
+   we don't have either.
+   Besides, groff has bug causing text right *before* .Bd -centered
+   to be centered as well.
  - .Bd -filled should not be the same as .Bd -ragged, but align both
    the left and right margin.  In groff, it is implemented in terms
    of .ad b, which we don't have either.  Found in cksum(1).

  - have a blank `It' head for `Bl -tag' not puke
+ - check whether it is correct that `D1' uses INDENT+1;
+   does it need its own constant?
  - 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)
+ - support translated section names
+   e.g. x11/scrotwm scrotwm_es.1:21:2: error: NAME section must be first
+   that one uses NOMBRE because it is spanish...
+   deraadt tends to think that section-dependent macro behaviour
+   is a bad idea in the first place, so this may be irrelevant
  - When there is free text in the SYNOPSIS and that free text contains
    the .Nm macro, groff somehow understands to treat the .Nm as an in-line
    macro, while mandoc treats it as a block macro and breaks the line.

  --- missing man features -----------------------------------------------
- - groff an-ext.tmac macros (.UR, .UE) occur in xine(5)
-   reported by brad@  Sat, 15 Jan 2011 15:45:23 -0500
  - -T[x]html doesn't stipulate non-collapsing spaces in literal mode
  --- missing tbl features -----------------------------------------------
- - implement basic non-parametric .de to support e.g. sox(1)
+ - look at the POSIX manuals in the books/man-pages-posix port,
-   reported by naddy@ Sat, 16 Oct 2010 23:51:57 +0200
+   they use some unsupported tbl(7) features.
-   *** sox(1) still doesn't work, tbl(1) errors need investigation
+ - investigate tbl(1) errors in sox(1)
+   see also naddy@  Sat, 16 Oct 2010 23:51:57 +0200
  - allow standalone `.' to be interpreted as an end-of-layout
    delimiter instead of being thrown away as a no-op roff line
    reported by Yuri Pankov, Wed 18 May 2011 11:34:59 CEST
  --- missing misc features ----------------------------------------------
+ - italic correction (\/) in PostScript mode
+   Werner LEMBERG on groff at gnu dot org  Sun, 10 Nov 2013 12:47:46
+ - When makewhatis(8) encounters a FATAL parse error,
+   it silently treats the file as formatted, which makes no sense
+   at all for paths like man1/foo.1 - and which also contradicts
+   what the manual says at the end of the description.
+   The end result will be ENOENT for file names returned
+   by mansearch() in manpage.file.
+ - 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

-   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).

+   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);

-   Also, we don't want to break the line within the argument of:
-   .Fa "chtype tl"
- - .Ns should work when called at the end of an input line, see

-     .It Xo
-     .Op Ar line
-     .Cm a Ns Op Cm ppend Ns
-     .Op Cm !\&
