Hmm, I could have sworn "filefrag" did this, but it doesn't have any
mode that actually prints out a list of blocks, only the discontinuities
in the file... We are adding a new "extents" output mode to filefrag
which prints block mappings in a more useful manner, but it isn't in
upstream e2fsprogs yet.
