[tor-commits] [stem/master] Extra spaces were inserted into process names via set_process_name()

commit 8adc55c0139ff9f0925541be1254bea4767716ed

    Extra spaces were inserted into process names via set_process_name()
    
    After running set_process_name() ps would report spaces within our process
    name. For instance, when running our integ tests our name would become...
    
    p   y   t   h   o   n       .   /   r   u   n   _   t   e   s
    
    Fixed thanks to ragwater, who figured out that ctypes.memmove() wanted unicode
    rather than byte content...
