I went for something minimal.  For doing it "the right way", the patch 
is a bit longer:

The auto-detection is now performed by detect_music_type() (static 
helper).  This is intended to also be used by Mix_LoadMUS() in order to 
avoid the current code duplication.  I didn't change Mix_LoadMUS() 
though; if this patch is good enough to be committed, I will follow with 
another that will deal with Mix_LoadMUS().

I am attaching the new patch.  I'm not sure if the coding style follows 
your preferences, since it seems SDL_mixer's code does not follow a 
single style throughout, but deviates a bit (mostly spacing) so I was 
not sure which one to use.
