[ncl-talk] wind_component not working for single values?

[Dennis Shea]

As noted: This fails under 6.3.0 and  works for 6.4.0

My bad for not noting any 'bug fix' for the 6.4.0 release notes     :-(
    http://www.ncl.ucar.edu/current_release.shtml

My memory is that a change was made to specificall handle the case where
bot input arguments were scalars.
