+# Here is a fine piece of Git wizardry. It uses git stash to make sure that the
+# staged changes are correctly formatted:
+#
+# 1) Stash all changes (worktree + index)
+git stash push -u > /dev/null
+# 2) Apply only changes from index
+git show -p stash^2 | git apply 2> /dev/null
+# 3) Check with 'mix format' the staged changes
+mix format --check-formatted > /dev/null 2>&1
+retval=$?
+# 4) Undo changes brought from step 1
+git reset --hard > /dev/null
+git clean -f . > /dev/null
+# 5) Leave the repository as it was before
+git stash pop --index > /dev/null
