<DL>
<DD>Escape any whitespace found.
 
 The parent class takes care of the bulk of escaping.  But if any
 instance of escaping is found in the URI, then we ask for parent
 to do NO escaping.  Here we escape any whitespace found irrespective
 of whether the uri has already been escaped.  We do this for
 case where uri has been judged already-escaped only, its been
 incompletly done and whitespace remains.  Spaces, etc., in the URI are
 a real pain.  Their presence will break log file and ARC parsing.

<DT><B>Parameters:</B><DD><CODE>uri</CODE> - URI string to check.
<DT><B>Returns:</B><DD>uri with spaces escaped if any found.</DL>
