Fixer tool expects comments that follow specific pattern:

- For hash-style comments: comment starts with `# ` (hash following by whitespace) in the beginning of the string or after a whitespace.
- For slash-style comments: comment starts with `// ` (two slashes following by whitespace) in the beginning of the string or after a whitespace.

If comment doesn't follow this pattern, fixer tool will not preserve it.
