# We then commit the current sources and set the tag "old". (This keeps all mtimes unchanged.) | |
# Then we update worktree and index with "git reset --hard new". | |
# (This keeps mtimes of unchanged files unchanged and mtimes of changed files newer than unchanged files.) | |
# Finally we reset the index to "old". (This keeps all mtimes unchanged.) | |
# The changed files now show up as uncommitted changes. | |
# The final "git add -N" makes sure that files that were added in "new" do not show | |
# as untracked files, which would be removed by "git clean -fx". | |
