    gal_statistics_is_sorted: Initialize to avoid compiler warning
    
    After testing the previous two commits on another system, I saw a "maybe
    used uninitialized" compilation warning in this function. With this commit,
    it is being initialized to an absurd value (to be easily noticable). But it
    should never happen because we do put checks in multiple places.
