+- \\ in high-level macro arguments
+ Currently, \\ is expanded in two situations:
+ 1) macro and string definition (roff.c setstrn())
+ 2) macro argument parsing (mandoc.c mandoc_getarg())
+ For user defined macros, the second happens in time because of ROFF_REPARSE.
+ But for standard high-level macros, it only happens after entering the
+ high level parsers, which is too late because the code doesn't get
+ back to roff.c roff_res() from that point. Because this requires
+ distinguishing requests, user-defined macros and standard macros
+ on the roff_res() level, it is hard to solve without the parser reorg.

+- support mdoc(7) and man(7) macros inside tbl(7) code;

- look at the POSIX manuals in the books/man-pages-posix port,
they use some unsupported tbl(7) features.

-- 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.

+- Vsevolod Stakhov (FreeBSD) needs either a markdown output formatter

i.e. when finding a literal tab character in fill mode,
and possibly change the wording of the warning message
