should this use getbool rather than get?

Line 1062 in 8fac187

 if boto.config.get('s3', 'use-sigv4', False): 

I am wondering if this line should be changed to use getbool() rather than get(). It seems even if "use-sigv4" is set to "false", it tries to use SigV4 because "false" is a non-empty string and thus truthy.
