I'm doing a script named git-remove-tree which removes the working tree
known to Git. It doesn't touch untracked files; it only deletes
directories if they are empty. The script seems to work, but because I'm
not very good at Git plumbing and there can be some corner cases which I
don't know about, I'd appreciate if more experienced users would have a
look. Is the following script safe?
#!/bin/sh
# git-remove-tree
is_wt=$(git rev-parse --is-inside-work-tree)
if [ "$is_wt" = false ]; then
echo "You must run this inside a working tree."
exit 1
elif [ -z "$is_wt" ]; then
exit 1
fi
top=$(git rev-parse --show-toplevel)
cd "$top" || {
echo "Can't go to top-level directory $top"
exit 1
}
git ls-tree --name-only -r -z HEAD | xargs -0r -- sh -c '
for f in "$@"; do
rm -f -- "$f"
d=$(dirname -- "$f")
[ "$d" = . ] || rmdir -p -- "$d" 2>/dev/null
done' dollar0_argument
echo 'Use "git reset --hard HEAD" to populate the working tree again.'

I think you should be able to reduce all of this to just
git read-tree --index-output=/tmp/empty.index -m -u \
4b825dc642cb6eb9a060e54bf8d69288fbee4904 # empty tree
rm -f /tmp/empty.index
(with the usual caveats about temporary files).
echo 'Use "git reset --hard HEAD" to populate the working tree again.'
