bug: git log --follow does not honour --author option

Hi,

I ran into this issue, see the output from git bugreport below. I first found it in version 2.30.2 from Debian Bullseye, but was able reproduce it also with a build from the next branch.

Best, Jaap

What did you do before the bug happened? (Steps to reproduce your issue)

A minimal working example reproducing the bug:

git init test-log-follow-author cd test-log-follow-author echo "Some contents." > foo git add foo git commit -m "Initial commit." --author "Myself <myself@example.com>" git mv foo bar git commit -m "Let's rename this." --author "Random other person <random@example.com>" git log --follow --author myself -- bar

What did you expect to happen? (Expected behavior)

I expected the last git log command to show the initial commit made by myself.

What happened instead? (Actual behavior)

No commits show up.

What's different between what you expected and what actually happened?

The --author option doesn't seem to find commits across renames when using --follow, except for when searching the author who renamed the file: these are found, and all commits also show up as expected when no --author argument is used.

Anything else you want to add:
