[setup]
echo "The glass is full of water." > glass
[win]
# Make a snapshot of the glass (a "commit")
git rev-parse HEAD
# Change the contents of the glass!
! test "$(cat glass)" = "The glass is full of water."
# And make a second commit!
git rev-parse HEAD^ && ! test "$(git show main:glass)" = "The glass is full of water."
