Print wp_no_robots only once

[tivnet]

This patch will not allow printing meta robots tag more than once (if called by different plugins).

P.S.
I'd think about a more universal method, wp_meta_robots({parameters}), which every developer should use. Or something in the lines of "wp_register / wp_enqueue" - for all meta tags.

Could you please make any resolution on this?
Thank you!

This is a utility function - it's not a bug if it is called more than once.

Sergey, this change is so obvious (to me) and so tiny - yet it stays here for 2 months? This meta must not be printed more than once.

That's what I'm curious about. Why must it not be printed more than once? Do search engines ignore it all together? Does the page not validate? Does the browser refuse to load the page?

This isn't necessarily a utility function. It should be attached to wp_head. It can be used with add_action() repeatedly and it'll still only be printed once.

Replying to nacin:
You know, you are right it really does not matter. There should be a good function that collects and prints meta tags all together, with all possible options, and without duplication. As it is now - it's better just not to use in own development, and leave it for the core internal use.

Let's scratch this ticket.
