This is difficult to test, but apply the patch and run:
`dot -T png -o file.png committers-doc.dot`
The generated file can be seen [[]https://people.freebsd.org/~fernape/file.png | here]
What I did was to take the current value of `internal/admin/access` for the doc
repository, do some `grep -v` to get the people who don't have access anymore
and then dig a bit the output of `git log`.
Note that I am unable to find when the commit bit for `jim@` was taking in.
