-- lines containing blank characters, and nothing else,
-  in literal context (.Bd -literal):
-  groff outputs just blank lines "\n"
-  mandoc outputs blanks to the left margin,
-  then the number of balnks minus one
+- .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.
+
+- .%T should be quoted, not underlined, when .%J is also present,
+  to better distinguish the contents of .%T and .%J,
+  see for example OpenBSD cat(1)
+
+- 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).
+
+- .Bd -literal and .Bd -unfilled are *not* identical.
+  In -literal, tabs are 8 spaces.
+  In -unfilled, tabs are 5 spaces, just like in -filled and -ragged.
+  See the CCDF_* display in OpenBSD ccdconfig(8).
+
+- .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);
+  reported by jmc@ on discuss@  Fri, 29 Oct 2010 13:48:33 +0100
+
+- It seems that .TP does not want TWOSPACE after the tag;
+  see bashbug(1); reported by naddy@
+
+- Header lines of excessive length:
+  Port OpenBSD man_term.c rev. 1.25 to mdoc_term.c
+  and document it in mdoc(7) and man(7) COMPATIBILITY
+  found while talking to Chris Bennett
