This is a purely cosmetic change

Browse Source 
but it outlines what I'm GOING to do to this file.
It's sort of an unignorable notification of coming changes..

This is a bit rude I understand.. but I can't afford to haqve the
diskslice code  drifting off too much further from a workable system
and I think I need to jump in now to make it obvious what has to be done
before it's too late.

appologies to bruce in advance.
