Commands like `grep()` provide option parsing, which is awesome. But it would be great if I could tell shelljs when to **not** do option parsing. In the shell, sometimes I want to actually `grep` *for* `-v` in a file, instead of using it as [an option](https://github.com/shelljs/shelljs#grepoptions-regex_filter-file--file-). In the shell: ```sh $ grep -- -v file.txt ``` Proposed shelljs feature: ```js shell.grep('--', '-v', 'file.txt'); ```
