在Vim中设置了
set wrap
set linebreak
做到了软折行（soft-wrap），但是折行前没有行号。
设置了：
set cpo+=n
set showbreak==>
可以得到下面的效果：
但还是没有行号。因为老师要求用Latex写论文，自己又习惯了Vim，所以希望可以在折行的地方也加上行号，方便阅读。
If you want Vim to show display lines, not the actual, physical lines, that's not possible. It also doesn't make sense, since no movement command except gj / gk works on display lines, and you cannot use them in :[range].
If you want wrapped/broken lines to actually be new lines, why don't you actually make them new lines?
gqq reformats the current paragraph using the textwidth settting
To get automatic formatting going:
set fo=tcrwa textwidth=80
Now, whenever you're type your text will wrap around. On auto-wrap, a trailing space is left on the previous line indicating it isn't the end of a paragraph yet.
