It is safe, and "+" does not represent blanks.  The "+" character is
used to separate keywords in a URL generated by an ISINDEX query,
but those separators are not equivalent to blanks.  Since the query part
is generated, there is no need for "+" to be reserved in the URL syntax,
which is why it is not reserved in RFC 1738.
