We need the -wait option for nc that allready was
proposed with patch #403647.
As we startnedit through a script, doing some automatic
conversions for files, from a file-manager which should
handle all nedit sessions via a single server, and
cleanup temp. files after each nedit ends.
So starting via nc currently cleans the file up, before
even nedit can open it.
So we need an option to nc (-wait) which will wait with
returning unless the files specified are closed.
