not bug

From: Jean-Louis Maltret <jlm(at)not-real.eiffel.univ-mrs.fr>

I have been using old version of swish for 6 months and I have
already fixed the major "not" bug. I discovered only recently
swish-e (information came very late in France) but it seems
that the "notresultlist" function is still bugged, because of
the "% 128" system of file numbers. Here is the piece of code
that I have written in old version, taking in account the fact
that filenums are dropped % 128 .


With congratulations to the team which maintains this very useful tool.
