git log: support "auto" decorations

Browse Source 
This works kind of like "--color=auto" - add decorations for interactive
use, but do not change defaults when scripting or when piping the output
to anything but a terminal.

You can use either

    [log]
         decorate=auto

in the git config files, or the "--decorate=auto" command line option to
choose this behavior.
