Autosquash can't squash commits that modify non-formula files

[dpo]

brew config output

N/A: issue occurs on GitHub Actions VM

brew doctor output

N/A: issue occurs on GitHub Actions VM

Verification

• I ran brew update and am still able to reproduce my issue.
• I have resolved all warnings from brew doctor and that did not fix my problem.

What were you trying to do (and why)?

Merge a PR in a tap by labeling it with "pr-pull". The PR in question only modifies the version of a formula: https://github.com/coin-or-tools/homebrew-coinor/pull/81/files

What happened (include all command output)?

The job fails with the error message

Error: Autosquash can't squash commits that modify non-formula files.

https://github.com/coin-or-tools/homebrew-coinor/runs/5365992002?check_suite_focus=true#step:4:20

What did you expect to happen?

Expected the bottles to be published and the PR to be merged.

Step-by-step reproduction instructions (by running brew commands)

The issue occurs in GitHub Actions on a tap, not by manually running brew commands.

The issue was reported here: https://github.com/Homebrew/discussions/discussions/3033
and I was advised to open an issue on this repository.

Specifically, the bug is that this line fails to take into account that formula files can lie outside of a Formula subdirectory (or in HomebrewFormula):

brew/Library/Homebrew/dev-cmd/pr-pull.rb

Line 227 in b4244bb

next if %r{^Formula/.*\.rb$}.match?(file)

Given these commands exist primarily for our workflow: I'm tempted to say "we'll review a PR to fix this but don't plan on doing so ourselves" (unless you'd like to, @Bo98).

The workaround also seems to be pretty straightforward: just move your formulae into a Formula or HomebrewFormula subdirectory.
