Run tools against code blocks in documentation. This allows you to run linters, formatters, and other tools against code examples in your documentation files.
Reject --temporary-file-name-template values that could resolve outside the temporary directory, preventing accidental overwrite or deletion of unrelated files. See #1211 https://github.com/adamtheturtle/doccmd/issues/1211__.
Support configured file extensions with more than one dot (for example --rst-extension=.test.rst) for both direct files and directory discovery (#1212 https://github.com/adamtheturtle/doccmd/issues/1212_).
