Subject: [PATCH] Defer sanity checks of dir attribute to the point where the
 fileset will be used for the first time. This will enable things like

<project default="main">
  <fileset dir="tmp" id="tmpfiles">

  <target name="prep">
    <mkdir dir="tmp" />
  </target>

  <target name="main" depends="prep">
    <copy todir="foo">
      <fileset refid="tmpfiles" />
    </copy>
  </target>
</project>
