This allows the script to recognise some matches that it would miss
before and avoid listing them as missing.
Ideally, the script should be able to understand the globs in
`CODEOWNERS` and correctly find matching file-system paths.However, for
the limited purposes of the script (and for just a couple of relevant
globs), implementing this would be an overkill.
Implemented the "manual expansion" instead.
(We might revisit, if the needs change.)
