文献类型为@mvbook，书名后未能输出[M]？

[superfluous-man]

现有一则@mvbook文献条目如下：

@mvbook{FengQi-2019-JiHeLunDaoYinJiBenLiLun, title = {集合论导引：基本理论}, author = {{冯琦}}, date = {2019}, series = {现代数学基础丛书}, volume = {1}, number = {178}, publisher = {{科学出版社}}, location = {{北京}}, volumes = {3} }

参考上一条Issue中的办法，修改了BBX文档，隐藏了标题后的卷数信息，保留了文献类型标识后的卷数信息。

引用上述文献后，文献列表输出的是：

冯琦, 2019. 集合论导引:基本理论. 第1卷. 3 vols. 现代数学基础丛书: 178. 北京: 科学出版社.

这个格式有总卷数（3 vols.）信息，但没有[M]文献类型标识。

而将bibtex内容调整为@book类别，则文献列表输出的是：

冯琦, 2019. 集合论导引:基本理论[M]. 第1卷. 现代数学基础丛书: 178. 北京: 科学出版社.

这个格式有[M]文献类型标识，但没有将总卷数（3 vols.）列出。

@book{FengQi-2019-JiHeLunDaoYinJiBenLiLun, title = {集合论导引：基本理论}, author = {{冯琦}}, date = {2019}, series = {现代数学基础丛书}, volume = {1}, number = {178}, publisher = {{科学出版社}}, location = {{北京}}, volumes = {3} }

如何调整相关设置，以使@mvbook文献条目列表输出的格式为：

冯琦, 2019. 集合论导引:基本理论[M]. 第1卷. 共3卷. 现代数学基础丛书: 178. 北京: 科学出版社.

3 vols 汉化或英文亦可。

感谢！

改的要稍多一些，卷通常是跟标题放一起的。

感谢！

按这个思路，照葫芦画瓢临时性魔改了一下，将卷数调整至title与subtitle之间，并略改标点样式，得到以下中文条目的格式效果：

示例中的第3卷是略去subtitle的测试格式。

[zepinglee]

按照国标的示例，似乎应该按照这个格式：“题名: 卷次 分卷书名”。
