[Plugin: WP Tweet Button] Force removal of www for local URL shortening

Hello,

Referring to this post:
http://wordpress.org/support/topic/plugin-wp-tweet-button-use-wp-local-urls-own-domain

I just have one more thing about the Local URL,

If a blog is using the www, it already has canonicalization that redirects the non www to the www URL.

It means that instead of generating a URL like this:

http://www.example.com/?p=123

the plugin should generate a URL like this:
http://example.com/?p=123

This will save 4 characters.

Please add option for this or make it automatic. (It should remove the www. from the “WordPress 3 shortener function” output)

Thanks.
