Allow empty lines while looking for diff (between `---expected` and `FAILED`). This can happen when there is `Locations outside the test directory` since an empty line is printed after that warning message (this output can be interleaved with the diff due to parallel execution).
This script can be used to go over `codeql test run` expected/actual log
output from actions CI checks for a PR, and apply patches locally to
make the tests pass.
Designed for use by GitHub employees, since it needs access to internal
CI runs. Just run this tool while the branch for the PR is checked out!
You need the `gh` cli tool installed and authenticated.
Example can be seen in https://github.com/github/codeql/pull/12950
