Option values cannot start with dash

I have an option to provide a key to a utility. The key value in one instance happens to start with "-". So running:

`utitility.exe --key -gobbledygook123`

produces an error message:

ERROR(S):
Option 'g' is unknown.
Required option 'key' is missing.

重现报告中的命令 `utitility.exe --key -gobbledygook123`，并跟踪将该值当作另一个选项处理的命令行选项解析路径。完成标准是：接受以 `-` 开头的键值，并且解析器不再报告选项 `g` 未知，也不再报告必需的 `key` 缺失。
