Processing the word argument to -W honors shell quoting, in order to
provide a simple way to return words containing shell metacharacters and
characters in $IFS. There is a sentence to this effect in the texinfo
documentation, but that sentence is missing from the manual page.  I will
add some clarifying text and make sure it appears in the man page.
