Mergemaster

[Doug Hardie]

I have been following the discussion on mergemaster and one item is a  
bit annoying.  You can use -U in the command args which sets  
"AUTO_UPGRADE=yes".  That flag is not in mergemaster.rc.  It could be  
easily added to the rc file, but I suspect it would conflict with -p.   
Hence it seems like if "unset AUTO_UPGRADE" were added to the -p  
section then it would work.  It would be helpful to be able to include  
it in the rc file so I don't have to remember the options each time.
