sed替换文本中的行号

lnzfm

从网页里复制下来的代码经常是带着行号,而且多行合并成了一行,例子如下:
1. this is line1 2. this is line2 3. this is line3 4. this is line4 5. this is line5 6. this is line6 7. this is line7 8. this is line8 9. this is line9 10.this is line10
求各位兄弟姐妹帮忙将连续数字和点的字符串用sed替换成换行符

1. this is line1
2. this is line2
3. this is line3
4. this is line4

不会用sed,真拙急啊

很抱歉,上面我发的预期结果写错了,我重新编辑了贴子,希望得到的输出结果以下面结果为准:
this is line1
this is line2
this is line3
this is line4

谢谢,参与回复帖子的同学,请继续

建议在浏览器里面查看网页源代码，这样复制就不会合并到一行了。

真实文本不一定是数字空格结尾呢

很抱歉,我把期望的结果写错了,希望得到的输出结果里应该是去掉开头的数字和小数点的,如下:
this is line1
this is line2
this is line3
this is line4
