Ambiguity in 3.1.6.2

https://www.w3.org/TR/clreq/#h-adjustment_of_adjacent_punctuation_marks

In principle, any two adjacent punctuation marks that are 2 em wide should be reduced to 1.5 em. Following the same principle, they may be reduced to 1 em for certain typographic styles.

Suggestion from @r12a (in order to avoid ambiguity):

In principle, any two adjacent punctuation marks that together are 2 em wide should be reduced to 1.5 em. Following the same principle, they may be reduced to 1 em for certain typographic styles.

I propose changing the Chinese translation from [原则上的调整度应为：如果任意两个相邻标点符号占用2个字宽，应当缩减成1.5个字宽。在此原则上，允许排版风格进一步调整让两个符号只占1个字宽。] to [基本原则是，任何两个相邻的标点符号如果占据2个字宽，应缩减至1.5个字宽。按照同样的原则，某些排版风格可以将它们缩减至1个字宽。].
