可以忽略注释/排除修订的Diff工具?

版本1。

This is a sentence
Here is an address
What's going on here

版本2。

1 This is a sentence
2 Here is an address
3 What's going on here

版本3。

//added periods
1 This is a sentence.
2 Here is an address.
3 What's going on here.

是否有一个用于windows的diff工具可以查看版本1、排除版本2和版本3,并生成只显示句点的视觉diff?我一直在做简单的大规模重构,它真的把森林从树上遮住了。
