Code review comment for lp:~craighewetson-deactivatedaccount/bzr/update_with_local_commit

I feel that until the update handles the presence of local changes and local commits better; this patch will make sure the user doesn't mess his workspace up.

I've seen this problem happen to collegues that have made changes to dozens of files (i.e by renaming a single method) and then after the update, starting pulling there hair out because they forgot to commit locally. :)
