 @code{\salutation[John]} gives @samp{Dear John:}.  And
 @code{\salutation[]} gives @samp{Dear :}.
 
+A command with no arguments that is followed in the source by a space
+will swallow that space.  The solution is to type @code{@{@}} after the
+command and before the space.
+
+The braces around @var{defn} do not delimit the scope of the result of
+expanding @var{defn}.  So @code{\newcommand at domain.hid #1@}}
+is wrong since in the sentence
+
+ at example
+The \shipname at domain.hid@} met the \shipname at domain.hid@}.
+ at end example
+
+the words @samp{met the} will be in italics.  An extra pair of braces
+ at code{\newcommand at domain.hid #1@}@}} fixes it.
