+ Many issues are annotated for difficulty as follows:
+  - loc = locality of the issue
+     *    single file issue, affects file only, or very few
+     **   single module issue, affects several files of one module
+     ***  cross-module issue, significantly impacts multiple modules
+          and may require substantial changes to internal interfaces
+  - exist = difficulty of the existing code in this area
+     *    affected code is straightforward and easy to read and change
+     **   affected code is somewhat complex, but once you understand
+          the design, not particularly difficult to understand
+     ***  affected code uses a special, exceptionally tricky design
+  - algo = difficulty of the new algorithm to be written
+     *    the required logic and code is straightforward
+     **   the required logic is somewhat complex and needs a careful design
+     ***  the required logic is exceptionally tricky,
+          maybe an approach to solve that is not even known yet
+  - size = the amount of code to be written or changed
+     *    a small number of lines (at most 100, usually much less)
+     **   a considerable amount of code (several dozen to a few hundred)
+     ***  a large amount of code (many hundreds, maybe thousands)
+  - imp = importance of the issue
+     *    mostly for completeness
+     **   would be nice to have
+     ***  issue causes considerable inconvenience
+ Obviously, as the issues have not been solved yet, these annotations
+ are mere guesses, and some may be wrong.

+ - The abort() in bufcat(), html.c, can be triggered via buffmt_includes()
+   by running -Thtml -Oincludes on a file containing a long .In argument.

- - \\ is now implemented correctly
+ - .Bd -centered implies -filled, not -unfilled, which is not
-   * when defining strings and macros using .ds and .de
+   easy to implement; it requires code similar to .ce, which
-   * when parsing roff(7) and man(7) macro arguments
+   we don't have either.
-   It does not yet work in mdoc(7) macro arguments
+   Besides, groff has bug causing text right *before* .Bd -centered
-   because libmdoc does not yet use mandoc_getarg().
+   to be centered as well.
-   Also check what happens in plain text, it must be identical to \e.
+   loc ***  exist ***  algo **  size **  imp **  (parser reorg would help)
  - .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).
+   loc ***  exist ***  algo **  size **  imp **  (parser reorg would help)
  - implement blank `Bl -column', such as
    .Bl -column
    .It foo Ta bar
    .El
+   loc *  exist ***  algo ***  size *  imp *
  - explicitly disallow nested `Bl -column', which would clobber internal
    flags defined for struct mdoc_macro
+   loc *  exist *  algo *  size *  imp **
  - In .Bl -column .It, the end of the line probably has to be regarded
    as an implicit .Ta, if there could be one, see the following mildly

  - inside `.Bl -column' phrases, punctuation is handled like normal
    text, e.g. `.Bl -column .It Fl x . Ta ...' should give "-x -."
-Line 95
+Line 162
 Line 95
 Line 162
    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
+ - check whether it is correct that `D1' uses INDENT+1;
+   does it need its own constant?
+   loc *  exist **  algo **  size *  imp **
- - 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)
+ - 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
+   loc **  exist **  algo **  size *  imp **
  - 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.

+ - 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

  - 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

+   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.
+   loc *  exist *  algo *  size *  imp ***
  - 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
-   the following code in vi(1):
-     .It Xo
-     .Op Ar line
-     .Cm a Ns Op Cm ppend Ns
-     .Op Cm !\&
-     .Xc
-     The input text is appended after the specified line.
  - 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

- - In man(7), the sequence
-     .SH HEADER
-     <blank line>
-     .PP
-     regular text
-   should not produce any blank lines between the header and the text,
-   see for example rsync(1).

- - In man(7), the sequence

-     .IP
-     .IP "tag"
-     indented text
-   should produce one, not four blank lines between the regular text
-   and the tag, see for example rsync(1).
-   Likewise,
-     regular text
-     .IP
-     indented text
-   should produce one, not two blank lines in between, and
-     regular text
-     .IP
-     .RS
-     .IP tag

    with user-defined macros, leading to random breakage.
