Yea, OK, I know what that is.  I busted PackIndex.isTOC.

I asked it to compare a 4 byte array (TOC only) to an 8 byte array
(TOC + version) and of course 4 != 8 so it fails.  Thus all V2
index files look like V1 files.  Only they aren't; and then all
hell breaks loose when we start treating parts of the V2 index as
different sections of the V1 index.

I'll post a replacement patch in a minute.

That's because Marek's branch includes additional tests for features
he added to PackIndexV2.  But all PackIndexV2 reading is busted.
