Vim 语句运动

Question

根据 Vim 的手册:

A sentence is defined as ending at a '.', '!' or '?' followed by either the end of a line, or by a space or tab.

然而 (和 )如果句子之间只有一个空格，则正常模式运动似乎没有效果:

First sentence. Second sentence.

但是 (和 )如果句子之间有多个空格，则按预期工作:

First sentence.  Second sentence.

我的问题是为什么 (和 )当句子用一个空格分隔时没有影响？

Answer 1

此行为记录在 Vim's manual (:help sentence) 中:

If the 'J' flag is present in 'cpoptions', at least two spaces have to follow the punctuation mark; Tabs are not recognized as white space.
