[projects/git-slug: 148/170] Print header only when something has been fetched

[glen]

commit 2cf9de3641fb244b319eaf062317f3e053e60f33

    Print header only when something has been fetched
    
    The algorithm to discover if there is something to fetch can sometimes
    give false positive, as the remote heads can be packed. So sometimes the
    header was printed even when nothing has been fetched.
