--verbose option works in a "non-standard" way #1
Description
Currently the --verbose / -v option expects an integer argument for specifying the verbosity. It's more common to just increase verbosity with --verbose / -v without arguments, and use multiple options for higher verbosity (e.g. OpenSSH uses this syntax).
See http://code.google.com/p/hardlinkpy/issues/detail?id=5 for an example where this has caused confusion and unexpected (even dangerous) behaviour.
