    git: Tell git send-email where to send patches.
    
    I've been using
    
      git send-email --annotate --suppress-from --to=gcc-patches@gcc.gnu.org \
      ${@:-HEAD^} ':!*/ChangeLog' ':!*configure'
    
    for sending most patches, but it occurs to me that it would be useful to put
    the To: address in the configury.
    
    If someone were feeling ambitious, they could write a script to analyze a
    patch and add the relevant maintainers to To: or CC:.
    
    contrib/ChangeLog:
    
            * gcc-git-customization.sh: Configure sendemail.to.
