builtin-remote: Fix missing newline at end of listing of pushed branches

Without this the output of 'git remote show' does not end with a new-line:

bash> git remote show repo
* remote repo
  URL: repo.or.cz:/srv/git/kdbg.git
  Tracked remote branches
    maint master mob
  Local branch pushed with 'git push'
    +master:masterbash>
