loc ** exist *** algo *** size * imp ***
-- \\ 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.

loc * exist *** algo *** size ** imp **
-- .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.
- 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).
