Subject: [PATCH] Added a script that counts Assisted-by attributions
 completely

Git reads trailers only from a block at the very end of a commit message. A
squash merge concatenates the branch's messages, so every trailer but the last
ends up mid-message, and an indented trailer is skipped as well. Both forms are
real attributions and both are invisible to the trailer parser, which is what
the project has been using to answer which agents touched a file.

The script reads whole commit bodies instead. It groups by value, or lists one
line per commit with --list, and takes a revision and a path the way git log
does.

On dev it reports 163 attributions where the trailer parser reports 122, so a
quarter of the record was unreachable. The difference is entirely squashed and
indented trailers, not new commits.
