messages_remove_callback_values cookies

[DJPaul]

The cookies used by messages_remove_callback_values() and messages_add_callback_values() are prone to causing errors if you try to programatically send a message - an example of it was causing errors about trying set cookies after the page header had been sent to the client's browser.

I would like an argument added or some behaviour to avoid the cookies being set - it saves me and others duplicating a large function to only comment out one line.

You shouldn't be adding messages after you've started to output the page. Run all of your code first, set the message, then output.

Unless I'm misunderstanding what you are saying, if so, please comment.
