--replace overwrote each input file unconditionally, bumping its mtime even when the formatted output was byte-identical. Compare against the file's current contents first and only write on a real difference, so already-formatted files keep their mtime. This makes the tool idempotent for change-detecting callers Signed-off-by: Paul Meyer <katexochen0@gmail.com>
