 From reading the man page, yes.  From experience, no.  I think the
man page is wrong here, but i haven't looked into the code.  My
experience says that dump always ``thinks'' in terms of blocks with
one kilobyte per block.  The `b' is the tape blocking factor only
(number of kilobytes per write()), but is not used otherwise in size
calculations.

Somebody should review the code, and correct the man page.
