I assume it's because of the preceeding whitespaces from wc, unfortunately the
error channel from the script is discarded so I'm only 99.98% sure ;) (imho
stderr should be echoed back to the console).

Maybe someone else with a similar setup can check if this problem is
reproducable? (FreeBSD 5.4-STABLE and FreeBSD 6.0-STABLE, do "update slots" for
a check). At least here it's definitely not working without the the '|bc' but
working with it.
On the other hand I don't think the additional "bc" will break anything (at
least) in the *BSD world (which is where chio is used) since "bc" is part of
base. I guess a line in the release notes is due anyway.
Kind regards,
Alex
