- .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.

- .als only works for macros in mandoc, not for user-defined strings.

Also, the "val" field in struct roffkv would have to be replaced

with a pointer to a reference-counted wrapper, and an alias

would have to point to the same wrapper as the original.

.als to undefined does nothing; the alias is not created.

.rm'ing the original leaves the alias to point to the old value.

.de .als .de changes both, but

.de .als .rm .de only changes the new value, not the alias.

- roff string condition comparisons fail when vars contain quotes:

.ds s '

.if '\*s'' \&...

hard to fix because of the basic architecture (string replacement

happens before roff(7) syntax parsing)

- 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.

This may not be the ideal solution after all: eqn(7) matrices

are lists of columns, so Avi's proposal would show each *column*

on its own *line*, which is likely to cause confusion.

A better solution, but much harder to implement, would be to

actually show the coordinates of column vectors on different

terminal output lines, using the clumnated output facilities

developed for .Bl -tag, .Bl -column, and also used for tbl(7).
