A suggestion for column-specific list-filtering for
PluggableMultiColumnListMorph:

   - when the filter string starts with one space, the remainder of the
filter string matches on the first column only
   - when the filter string starts with two spaces, the remainder of the
filter string matches on the second column only
   - etc.
   - when the filter starts with a non-space character, the whole string
applies and all columns are searched

Best,
  Chris
