Or it would be roughly a 5 line change to e2image (3 for option
parsing, 1 for the usage line, and 1 to the if statement in
write_raw_image_file() :-) to add an option to extend the "raw dump"
functionality to also dump the data blocks of files, at which point it
would create a sparse file containing only the used blocks in the
filesystem for you, automatically.
