    Clarify g_spawn_*() behaviour without full path
    
    Document the previously uncovered case of calling g_spawn_async_with_pipes()
    without a full path but no G_SPAWN_SEARCH_PATH. This runs programs from the
    current directory, which might be unexpected and even dangerous in some corner
    cases.
