Subject: [PATCH V2 1/2] fetch --prune: Always print header url

From: Tom Miller <[email-masked]>
Date: Thu, 19 Dec 2013 16:57:11 -0600

If "fetch --prune" is run with no new refs to fetch, but it has refs
to prune. Then, the header url is not printed as it would if there were
new refs to fetch.

Output before this patch:

	$ git fetch --prune remote-with-no-new-refs
	 x [deleted]         (none)     -> origin/world

Output after this patch:

	$ git fetch --prune remote-with-no-new-refs
	From https://github.com/git/git.git
	 x [deleted]         (none)     -> origin/test
