man page says nothing on rounding for -size

[Roman B.]

Hi,

recently I was puzzled by the output of

$ find -size 1M

As a result, I've got files that are smaller than 1Mb. However, I
wasn't able to find anything that describes this behavior in find's
man page. Rounding up is explained only in full documentation.

I suggest to add one sentence about rounding up to man page also, to
make it complete.

Regards,
Roman
