Fix "copy address" in Mail, Mac OS X Snow Leopard

I frequently right-click on senders and recipients in Snow Leopard and select "Copy Address" to copy their email addresses. Mail.app's default behavior in Snow Leopard is to copy both person's name and email address instead of just the email address. So you might get "Eric Cheng " instead of just "foo@bar.com". To change the behavior of "Copy Address", open a Terminal window and enter the following command:

> defaults write com.apple.mail AddressesIncludeNameOnPasteboard -bool NO

Restart mail, and the behavior will change.
