Re: [PATCH 5/6] Teach "fsck" not to follow subproject links

The small detail in the last step is wrong, though.  Even if

The superproject *is* a ref.

You cannot prune the subprojects on their own. That's the *only* real 
special rule about subprojects. Exactly because pruning them on their own 
is not a valid op to do.

It's the same way with an source of "alternate" objects (or a shared 
object directory) - you'd better not prune them, because other projects 
may have refs to them that you don't know about locally. So this isn't 
somethign new to subprojects.
