a macro and the \} terminating a conditional block, e.g.

- to be revisited after OpenBSD 4.8 tree unlock
-
-- implement \\
- in plain text, identical to \e
- as a macro argument, identical to \ i.e. escaping the next character
- We do not have macro definitions yet; if we implement them,
- \\ must behave in a macro def like in a macro argument,
- and when using the macro, it must expand yet again.
-
-- implement basic non-parametric .de to support e.g. sox(1)
- reported by naddy@ Sat, 16 Oct 2010 23:51:57 +0200
- *** sox(1) still doesn't work, tbl(1) errors need investigation
-
-- clean up escape sequence handling, creating three classes:
- (1) fully implemented, or parsed and ignored without loss of content
- (2) unimplemented, potentially causing loss of content
- or serious mangling of formatting (e.g. \n) -> ERROR
- see textproc/mgdiff(1) for nice examples
- (3) undefined, just output the character -> perhaps WARNING
+- \\ is now implemented correctly
+ * when defining strings and macros using .ds and .de
+ * when parsing roff(7) and man(7) macro arguments
+ It does not yet work in mdoc(7) macro arguments
+ because libmdoc does not yet use mandoc_getarg().
+ Also check what happens in plain text, it must be identical to \e.
-- look at pages generated from reStructeredText, e.g. devel/mercurial hg(1)
- These are a weird mixture of man(7) and custom autogenerated low-level
- roff stuff. Figure out to what extent we can cope.

+- .%T can have trailing punctuation. Currently, it puts the trailing
+ punctuation into a trailing MDOC_TEXT element inside its own scope.
+ That element should rather be outside its scope, such that the
+ punctuation does not get underlines. This is not trivial to
+ implement because .%T then needs some features of in_line_eoln() -
+ slurp all arguments into one single text element - and one feature
+ of in_line() - put trailing punctuation out of scope.
+ Found in mount_nfs(8) and exports(5), search for "Appendix".

- A bogus .Pp between two .It must not produce a double blank line,
see between -R and -r in OpenBSD rm(1), before "update" in mount(8),
- or in DIAGNOSTICS in init(8).
+ or in DIAGNOSTICS in init(8), or before "is always true" in ksh(1).
+ The same happens with .Pp just before .El, see bgpd.conf(5).
Also have `It' complain if `Pp' is invoked at certain times (not
-compact?).
+- If the *first* line after .It is .Pp, break the line right after
+ the tag, do not pad with space characters before breaking.
+ See the description of the a, c, and i commands in sed(1).
+
+- If the first line after .It is .D1, do not assert a blank line
+ in between, see for example tmux(1).

- .Nx 1.0a
should be "NetBSD 1.0A", not "NetBSD 1.0a",
see OpenBSD ccdconfig(8).
on the next line, it must be indented by -width, not width+1;
see "rule block|pass" in OpenBSD ifconfig(8).
+- When the -width string contains macros, the macros must be rendered
+ before measuring the width, for example
+ .Bl -tag -width ".Dv message"
+ in magic(5), located in src/usr.bin/file, is the same
+ as -width 7n, not -width 11n.
+
- The \& zero-width character counts as output.
That is, when it is alone on a line between two .Pp,
we want three blank lines, not two as in mandoc.
should be indented, see e.g. rpc(3);
