Description of issue

I noticed the following behavior:

% brew bump --no-autobump firefox fastfetch
==> fastfetch
Formula is autobumped so will have bump PRs opened by BrewTestBot every ~3 hours.

==> firefox
Cask is autobumped so will have bump PRs opened by BrewTestBot every ~3 hours.

Is it intended that listed autobumped packages do not get skipped, despite the --no-autobump flag?

FYI, I am bumping packages obtained from grep -Eo 'homebrew[^}]+' repology.org.json | awk -F '"' '{print $5}' on the json downloaded from https://repology.org/api/v1/projects/?inrepo=homebrew&outdated=on, and skipping the autobumped ones would speed up the process.

I think the option is used without formula name but once you give it, brew explicitly try to bump.

I noticed that the same happens with --installed:

% brew bump --open-pr --installed --no-autobump
==> abseil
Formula is autobumped so will have bump PRs opened by BrewTestBot every ~3 hours.

==> actionlint
Formula is autobumped so will have bump PRs opened by BrewTestBot every ~3 hours.

==> aom
Formula is autobumped so will have bump PRs opened by BrewTestBot every ~3 hours.
