optparse, allowing both --foo and foo=99?

[Mark Harrison]

What's the magic to allow this?  If the value is not specified I
would like to use the default value of 1.

import optparse
p=optparse.OptionParser()
p.add_option("--debug")

(opts, args) = p.parse_args(['--debug=22']); print opts
(opts, args) = p.parse_args(['--debug']);    print opts

Many TIA!
Mark
