need to use the +0 trick, emphasys on very few !

It works, but in some cases (plans not understood by IBPlanalyzer) it
hangs completely, or does not show it properly on the treeview and so on.

I am working on a clone tool, I have tested a number of queries that
IBPlanalyzer does not understand and my tool nevers hanged, but still
can't parse all the plans, It's on the begining of the development, ( I
had not touched the code for a month or so, my time is very tight right
now) but I will take on ASAP.

When the tool is available I will let you know.
