One thing that needs to be changed in conjunction with this is
checkpatch.pl. When I try to use the new format, I get:

● a9b9b7e55379: btrfs: pre-allocate delayed dir index for non-overwrite rename
  ● checkpatch.pl: :2036: WARNING: Assisted-by expects 'AGENT_NAME:MODEL_VERSION [TOOL1] [TOOL2]' format

This patch fixes it for me, but I'm not sure it's restrictive enough.
Jon, feel free to fold this into the Documentation patch, or I can send
it separately if this seems right.
