After tagging the tip of "dev" branch with a "for-linus" tag and pushing both out, running $ git request-pull $url $last_release dev would produce an output asking the 'dev' branch of $url to be pulled, because that is what the user asked the message to say. We already detect this situation locally and include the contents of the tag in the output; if the $url has that tag, favor that tag (i.e. "for-linus") in the generated message over the branch name the user gave us (i.e. "dev") from the command line, to make the output look more consistent.
