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.

重現回報的命令 `utitility.exe --key -gobbledygook123`，並追蹤將該值當作另一個選項處理的命令列選項解析路徑。完成標準是：接受以 `-` 開頭的鍵值，且解析器不再回報選項 `g` 未知，也不再回報必要的 `key` 缺失。
