more terse push output

This changes the output of send-pack to match the new,
more terse fetch output. It looks like this:

To git://host.tld/path/to/repo
+ f3325dc...3b91d1c hasforce -> mirror/hasforce (forced update)
f3325dc..bb022dc  master -> mirror/master
! [rejected]        needsforce -> mirror/needsforce (non-fast forward)
* [new branch]      newbranch -> mirror/newbranch
* [new tag]         v1.0 -> v1.0

instead of:
