The 'help' keywird should be idnented by 1 TAB; the help text it self
should be indented by 1 tab and 2 spaces.

Furthermore, a "block" is not an absolute and perfectly-defined unit of
size. Under some conditions, a block may be 512 bytes, while under other
conditions it might be 4096 bytes; whatever, depending on the context,
and users are not really used to calculate in terms of blocks.

In this case, a block is 1024 bytes.

Also, we do not usually reference the default value, unless it is very
important.

Also, 'MB' refers to power-of-ten, while here we are mostly speaking 'MiB',
which is about powers-of-two:

What about:

    Specify the requested size for the filesystem, as a number of
    1024-byte blocks. The default, 61440, is worth a 60MiB filesystem
    (a little over 61MB).

Yann E. MORIN.
