Interesting for mke2fs on boot floppies [Bug#108165]

BFs should use a fixed version when it is ready.

Hello, I want to create a file system for an 2.0.x kernel. According to the
manpage, 2.0 didn't support any special features, so I use "-O none" as
described. Unfortunately, the created filesystem has an special feature though,
the sparse_option. This is easy to fix, I attached a patch. As far as I can
see, the author uses sparse_option by default, and made the "-r 0" option
disable it, but forgot the same for -O none.
