HTTP-header X-Pingback when pingbacks are turned off

[ose]

When switching off pingbacks under options/discussion, wordpress still sends an X-Pingback http header back to the browser.

This has two disadvantages:

• It causes unnecessary traffic by other servers trying to ping wordpress
• It reveals more information then necessary (essentially reveals that a server is running wordpress even if the web master tries to hide that fact in other places for security reasons).

Expected behavior: When pingbacks are disables, wordpress should not send the X-Pingback header to the browser.

The options under options..discussion are not a global option for whether or not pingbacks are enabled but are just the defaults for new posts.

There is no option to disable pingbacks.
