# usage: clean-branches
# Deletes any local branches which are ancestors of origin/main,
# and also any branches in origin which are ancestors of
# origin/main and are named like $USER-*.

# usage: clean-branches --reviews
# Deletes all the above mentioned branches as well as branches
# created by the scripts like `fetch-rebase-pull-request`. Be careful
# as this would also remove other branches with names like review-*
