YAML parsing sometimes gets sabotaged by asterisks that follow the end
of frontmatter (`---`). We now scope YAML parsing to only frontmatter
and we don't pass any contents that follow.
This adds a thread-safe RoundTripper that can be used for mocking HTTP
requests in tests. Incoming requests are matched based on their
contents, not the order the stubs were registered in.
If multiple templates are found, the user is prompted to select one.
The templates are searched for, in order of preference:
- issues:
1. `.github/ISSUE_TEMPLATE/*.md`
2. `.github/ISSUE_TEMPLATE.md`
3. `ISSUE_TEMPLATE/*.md`
4. `ISSUE_TEMPLATE.md`
5. `docs/ISSUE_TEMPLATE/*.md`
6. `docs/ISSUE_TEMPLATE.md`
- pull requests:
1. `.github/PULL_REQUEST_TEMPLATE/*.md`
2. `.github/PULL_REQUEST_TEMPLATE.md`
3. `PULL_REQUEST_TEMPLATE/*.md`
4. `PULL_REQUEST_TEMPLATE.md`
5. `docs/PULL_REQUEST_TEMPLATE/*.md`
6. `docs/PULL_REQUEST_TEMPLATE.md`
The filename matches are case-insensitive.
