@6543 still valid?

Yes, this is still an issue. It is very related to a problem I am having, which is the following:

I want to use a default merge message (by using .gitea/default_merge_message/MERGE_TEMPLATE.md). However, this removes the Reviewed-on and Reviewed-by lines in the merge message, and as far as I can see, there is no way to add them back in using the message template.

The reason for this is that the logic constructing the default-default merge message (i.e., if MERGE_TEMPLATE.md does not exist) is embedded in templates/repo/issue/view_content/pull.tmpl. If DefaultMergeBody (which is the templated MERGE_TEMPLATE.md is not set, the Reviewed-on and Reviewed-by lines are directly injected into the HTML template.

What would be desired is a way to inject these lines into the custom merge template, most likely via some variables.
