get_maintainer, b4, and CC: stable

Hi Joe, A recent mistake I made when using b4 was that I added a fixes tag, but forgot to Cc: stable in the commit message.

Speaking with Konstantine, it seems that b4 may just be importing the recommendations from get_maintainer.pl.

I suspect that either b4 or get_maintainer could see the Fixes tag and then suggest to Cc stable for me.

Should get_maintainer.pl make such recommendations?
