Yeah, it shows my really bad writing skill. :(

I meant I got your point of not using a temporary array.  And asked
additional question of your preference in a dummy entry.

Sorry for confusing you.

Btw, I found that printing 0.00% is useful for a case of field_sep and
GTK+ output.  So unless someone objects, I'll keep it.

Thanks,
