Passing -q --unmerged prevents update-index from erroring out when local
file changes are present.

>From git-update-index(1):

       -q
           Quiet. If --refresh finds that the index needs an update, the
           default behavior is to error out. This option makes git
           update-index continue anyway.

       --unmerged
           If --refresh finds unmerged changes in the index, the default
           behavior is to error out. This option makes git update-index
           continue anyway.
