+ While roff_parseln() prevents .ce and similar requests in the middle
+ of a tbl, the guard is no longer effective when the .ce is wrapped
+ in a roff block, for example a conditional. The resulting assertion
+ has never been seen in any real-world manual page.

-- \\ 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.

+- mandoc replaces all ASCII control characters except tab and line feed
+ with '?' during input. It would be better to replace them with
+ Unicode escapes in preconv_encode() or somewhere in the vicinity,
+ such that the already existing better replacement strings show
+ up in the output. Emulating groff is not desirable: groff replaces
+ 0x00, 0x0b, and 0x0d to 0x1f with the empty string (bad because
+ that's easy to overlook for the document author), 0x01 with '.'
+ (very confusing), and passes through 0x02 to 0x08, 0x0c, and 0x7f
+ raw (bad because that is insecure output). Remember that 0x07 may
+ need special handling because it is sometimes used for certain
+ delimiters, so it may need handling *after* roff.c rather than before.
+ reminded by John Gardner 16 Jun 2020 14:26:28 +1000
+ Actually, more ASCII control characters than just 0x07 may need
+ later handling because they can for example be used in macro names.
+ So they may need handling after roff(7) processing.

-Several areas can be cleaned up to make mandoc even faster. These are
-
-- improve hashing mechanism for macros (quite important: performance)
-
-- improve hashing mechanism for characters (not as important)
-
- the PDF file is HUGE: this can be reduced by using relative offsets
-- instead of re-initialising the roff predefined-strings set before each
- parse, create a read-only version the first time and copy it
- loc * exist ** algo ** size * imp **

* structural issues
************************************************************************
-- We use the input line number at several places to distinguish
- same-line from different-line input. That plainly doesn't work
- with user-defined macros, leading to random breakage.
