In description of sound_similar(), break up the markup for long
\code{} at each embedded space, so that the words will wrap. This keeps

\begin{funcdesc}{sound_similar}{string1, string2}
Compare the word in \var{string1} with the word in \var{string2}; this
is equivalent to
-\code{get_soundex(\var{string1})==get_soundex(\var{string2})}.
+\code{get_soundex(\var{string1})} \code{==}
+\code{get_soundex(\var{string2})}.
