-- .ce .if n .B two crashes because "return (*roffs[t].sub)" bypasses
- the "high level macros abort .ce" safeguard in roff_parseln()
- reported by espie@ in textproc/fstrcmp
+- .if n .ce in the middle of .TS data
+ afl case f1/id:000103,sig:06,src:009024+009105,op:splice,rep:2 (jes@)
+ 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.
+ This is too dangerous to fix before release because it requires
+ reorganizing the very delicate internals of roff_parseln(),
+ which risks causing more severe bugs.

+- wrong number of layout columns in tbl(7) code generated by -T man
+ https://savannah.gnu.org/bugs/?57720

+- 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.
