After the pass-name changes are taken out (this is the pre-reviewed bit
I'm currently trying to contribute to mainline), there is about 65 KB of
unidiff left from the ICI 2.0 branch.  That code needs a bit of GNU
reformatting, so I doubt it has been reviewed in its entirety.
As it looks like the pass-name changes can go into mainline soon, I want
to hold off creating a branch for the rest of the code till the former
changes are in mainline.
