- This was done with `brew typecheck --update --suggest-typed` which
(as of the previous commit) uses Spoom, yet another gem. I thought I'd
see how well it works. There are no Sorbet errors after these changes!
- Add sponsors updating to the existing man/completion/maintainer update workflow
- Hide/deprecated --fail-if-not-changed arguments and make them default behaviour
- Rename man-completions workflow to sponsors-maintainers-man-completions for consistency
- Make output and exit codes more consistent between these updating commands
- Fix maintainers updates not always being committed correctly
- I noticed this in a PR recently, maybe the maintainer didn't think
they would have to run `brew man` for this? In that case there's an
extra step after the PR is raised, red CI checks on the PR (which is
demoralising) and potentially requires a reviewer to point this out.
- This runs `brew man` if the `README` file has a diff as part of this
command. Then the user has to `git add .` and their PR is (probably)
good.
