It's basically good to me. But the position of insertion isn't
suitable and the message isn't correct.
Moreover, the same can be said about current print_usage().

So I'll merge this patch with change as below:

diff --git a/makedumpfile.8 b/makedumpfile.8
index cfd1270..61bd5f2 100644
--- a/makedumpfile.8

 Specify the buffer size in kilo bytes for analysis in the cyclic mode.
 Actually, the double of \fIbuffer_size\fR kilo bytes will be allocated in memory.


And I'll fix print_usage() too.
