Is it possible to use repeated non-option-argument options?

ssh, tar, and other common tools allow for multiple non-option-argument options and act on their total count. (Implementing this with getopt is pretty trivial).

e.g. `tar -cvf` and `tar -cvvf` produce different output.

Is there a way to do this with CommandLine? I did not see anything promising in the documentation or examples/source code I perused, but I may have missed something.

(This might just be related to #594, but the issue there seems to be with repeated options with _required_ option-arguments)

先檢視 CommandLine 的選項解析行為，以及 issue 中提到的文件、範例和原始碼，然後比較 #594 中的相關討論。當支援重複的非選項引數，並具備類似 tar 重複詳細程度旗標的計數相關行為，且測試涵蓋文件中的範例時，這項工作就完成了。
