[PATCH] fetch: show reference pointed by new tags

[Eric Engestrom <eric@engestrom.ch>]

Before, new tags had their names shown twice:
 * [new tag]         v4.5-rc6   -> v4.5-rc6

Instead, show the hash of the commit pointed to:
 * [new tag]         v4.5-rc6   -> fc77dbd

This is my first dive into git's code, so it's likely I'm not doing things
right. The first candidate for that is the literal `7`, which should probably
be a variable, but I couldn't find what I should use instead.

I'd be happy to fix this for a v2 :]

Cheers,
  Eric
