[chimps] The client may be better to check only HEAD

[kenichi ishigaki]

and use 'svn update' instead of 'svn co' because

1) it's much kinder to the svn server.

No need to explain.

2) I think people don't want to remove svn co'ed packages.

After all, we test because we want to use them, don't we?

3) svn info's Revision: or Last Changed Rev: may vary according to the
svn client's locale or language code.

It speaks Japanese for me.

4) if you want to loop it forever, why bother with older versions?

At least smoker's default should be non-0. Who wants to smoke
from the very beginning, especially for the packages that have revised
thousand times?

Cheers,

Kenichi
