If I type the following:

  JOptionP

and then press Cntrl-Space NB suggests JOptionPane.  If I press enter to let it
complete the code then NB will add an import for JOptionPane at the top of the
file.  But if instead I type this:

  JOptionPane.showM

and then press Cntrl-Space NB suggests the showMessageDialog()  method from
JOptionPane.  If I press enter to let it complete the  code then NB does *not*
add an import for JOptionPane.  I have to use  Fix Imports to then get the
import for JOptionPane.  That's inconvenient because it forces me to change the
way I work in order to get the auto-import functionality.  I would like for
auto-import to work regardless of how much of the class name I type.
