I did the 'git reset --hard' and it worked as expected. Just to check: 

/opt/lmi/src/lmi[0]$git status
On branch master
Your branch is behind 'origin/master' by 5 commits, and can be fast-forwarded.
  (use "git pull" to update your local branch)
nothing to commit, working directory clean
 
It's a rarity that I grab the release candidate after other commits but it's 
nice to have a backup plan in the event that it does.
