Wait... I just plugged this in:

sectors     blocks     frags-or-sectors
-------  *  ------  *  ----------------
blocks      frags          sectors

So you're saying that in v1, lfs_fsbtodb is zero; while in v2, lfs_fsbtodb
== lfs_blktodb - lfs_fbshift.  So the whole purpose of fragstofsb() is to
cancel out the effect of (lfs_blktodb - lfs_fbshift)?  Can I put that in a
code comment?
