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.
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.
