-- auto-Bk in the SYNOPSIS
- patch from kristaps@ Fri, 16 Jul 2010 14:51:24 +0200
- to be revisited after OpenBSD 4.8 tree unlock
+- \\ 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.
-- 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.

+- .Rv (and probably .Ex) print different text if an `Nm' has been named
+ or not (run a manual without `Nm blah' to see this). I'm not sure
+ that this exists in the wild, but it's still an error.
+- In .Bl -bullet, the groff bullet is "+\b+\bo\bo", the mandoc bullet
+ is just "o\bo".
+ see for example OpenBSD ksh(1)
+
+- The characters "|" and "\*(Ba" should never be bold,
+ not even in the middle of a word, e.g. ".Cm b\*(Bac" in
+ "mknod [-m mode] name b|c major minor"
+ in OpenBSD ksh(1)
+
+- 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).
+ Also have `It' complain if `Pp' is invoked at certain times (not
+ -compact?).
+
+- .Nx 1.0a
+ should be "NetBSD 1.0A", not "NetBSD 1.0a",
+ see OpenBSD ccdconfig(8).
+
+- In .Bl -tag, if a tag exceeds the right margin and must be continued
+ on the next line, it must be indented by -width, not width+1;
+ see "rule block|pass" in OpenBSD ifconfig(8).
+
+- 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.
+
+- When .Fn arguments exceed one output line, all but the first
+ should be indented, see e.g. rpc(3);
