probably saner to check where you are first, and have it conform to
some branch naming scheme; maybe someting like:

 - check you're on master
 - only consider branches that begin with first-last-/

-- 8< --
head=$(git rev-parse --verify HEAD)
master=$(git rev-parse --verify master)

if test "$head" != "$master"; then
    echo "You must be on master"
    exit 1

git branch --merged  |
sed -n -e 's/\ *//' -e '/^[^/][^/]\//p' |
xargs git branch -d
-- 8< --
