 - The space character joining .Dx .Fx .Nx .Ox (are these all?) to its
   argument is non-breaking.  See the cdio(1) HISTORY and many others.
 
-- .Bx uses a dash before its argument, not a space,
-  see for example the chpass(1) and column(1) HISTORY.
-  Besides, the second argument is capitalized, for example,
-    .Bx 4.3 tahoe .
-  produces 4.3BSD-Tahoe.

 - 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).
