Subject: [PATCH] CAM: Reintroduce matching pre-/postamble and help text for
 dynapath_4060_post.py

This change was introduced in 80a35a8765dcad9533aa685476c0be6b45b51656 (#24617) and
reverted without explanation in 21a597a85e1e22e17706efe2966a735995329a0d (#27202).
I assume it was reverted by mistake.

Note that for dynapath_4060_post.py, the original help text did not match the postamble,
illustrating the need to ensure the actual value matches the help text.
