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.

<!-- go.dev/issue/77177 -->

Response file (`@file`) parsing is now supported for the `compile`, `link`, `asm`, `cgo`, `cover`, and `pack` tools.
The response file contains whitespace-separated arguments with support for single-quoted and double-quoted strings, escape sequences, and backslash-newline line continuation.
The format is compatible with GCC's response file implementation to ensure interoperability with existing build systems.
