Making -i and -U default behavior for mergemaster (was: Re: svn commit: r179669 - head/sbin/rcorder)

Hi Doug,

The -i and -U options to mergemaster are such timesavers that I was 
wondering if they shouldn't be turned on by default. The attached patch 
makes this the default behavior and uses the -I and -X command line 
switches to turn it off.

Cheers.
