Add a filter to Auto Update debug email

[pento]

The core auto update notification email has a filter auto_core_update_email. There should be an equivalent filter for the debug email, too.

This would be particularly useful for admins who want to change the 'to' address of the notification email, they would expect the debug email to go to the same place.

Sounds good. I would like this that way I can pipe all emails directly to my error log.

The filter name should likely be automatic_updates_debug_email, for consistency with automatic_updates_send_debug_email.

The auto_core_update_email and auto_core_update_send_email hooks are particular to *core*, hence the difference in naming. I tried to use "automatic updates" in the general and "auto core update" in the specific.

No prob, renamed the filter to automatic_updates_debug_email in attachment:25756.2.diff​.

In 26013:

Add a filter to the Background Updates debug email, matches the filter used on the non-debug post-update emails. Props pento. Fixes #25756

Since this has been resolved, may I suggest updating the FAQ page with the question on it? ​https://wordpress.org/plugins/automatic-updater/faq/

Thank you.
