make prodigy command respect display-buffer-alist

closes #146

Thank you for the PR. Can you please check the tests? They don't pass on the CI.

I'm struggling to run the tests locally. Are the docs for running the tests up to date? Running make doesn't seem to do anything related to running the tests.

I'm struggling to run the tests locally.

you can always refer to how GitHub actions are implemented to learn how this works. This is in .github/workflows/test.yml:

$ make ci-dependencies
$ nix shell \
  --extra-experimental-features flakes \
  --extra-experimental-features nix-command \
  nixpkgs#nodePackages.coffee-script \
  --command make check

The Makefile is implemented with makel. Reading its documentation may help understand how things work.

The make ci-dependencies downloads dependencies (look at the first line of the Makefile) if they are not checked out in the parent folder already.

Then, the nix shell command downloads coffee-script before executing make check. The test that fails is in features/quit.feature and this doesn't need coffee-script. As a result, you can replace the whole nix shell command with just:

$ make test-ecukes

I think the overall issue with this PR is that the quit.feature test suite requires prodigy-mode to only be executed once (to keep the service marks when reopening prodigy) whereas the PR executes prodigy-mode each time the user re-opens the prodigy buffer.

The PR can be fixed with:

What still needs to be done is to add a new test scenario covering the new behavior.
