Remove local and remote tag annotation.

#!/bin/bash
#
# Remove annotation from local and remote tags.
# 
# This works fine for simple repositories.  However, if a tag checkout would
# result in a message about an untracked directory that cannot be removed, 
# things could get ugly.  Before trying this, make a backup that's not
# associated with the origin (i.e., `git clone repo repo-bak`) from which to
# recover.
