I'm sure we had this in the past and changed to what we have currently. Can't remember why... compressing filesystems maybe?

`wc -c` always shows the true size of a file -- that is, the number of bytes of information it contains, not a multiple of the block size. The compressed size can only be calculated by looking at the number of blocks allocated. This command is safe for all compressing/sparse- supporting file systems.
