I've noticed that gq does not work when I paste in a long line. For example, with a textwidth=72 and formatoptions=tcroqbnl, gq refuses to wrap this (in insert mode, I pasted the entire label contents, and then exited insert mode with ESC):

<label for="contact_reason_1">To get assistance with or to confirm a tire replacement recommendation</label>

如果我添加换行符（例如，在“to”之后），它就会换行。有趣的是，如果我把线重新连接在一起，它会很高兴地再次包裹它。所以 VIM 似乎在某种程度上记住了“哦，这是一个粘贴，不要包裹它”。

我如何关闭该功能？我希望 gq 在命令模式下always工作。服用l out of formatoptions似乎没有帮助（也不应该，这不是插入模式）。

澄清

Yes, I'm using a motion command, in particular, gq<Right>. formatexpr and formatprog are both unset. If it matters, this is in gvim on Debian GNU/Linux, vim version 7.2p284.

重现步骤

1. 在打开的文件上弹出 gvim。
2. Press i to get into insert mode, then type This is a long line. A long line. But not wrappable yet. Or yet. Soon.
3. Press ESC, then I. Type Now putting text in front of the long line. note: there is a space after the final period, can't get SO to show it, except when this note is here. FUN.
4. Press ESC, then A. Type And some after. note: space before the And, same SO problem.
5. Press ESC one last time. Now try gq<Left>, note it only wraps And some after.; I can't get vim to wrap the rest of the line (without going into insert mode and doing a line break by hand, then it works).

修复这种状态是可行的；在“now”后面添加一个换行符，然后单击“撤消”可以使换行再次起作用。 WTF。

gq isn't enough to wrap the text. You have to give it a motion over which to wrap (like gqj) or tell it to wrap the current line with gqq. Are you sure you're not just mistyping it?

如果不是，那是什么formatexpr and formatprg选项设置为，如果有的话？

Update
问题是 b 设置formatoptions。这告诉 Vim 仅对上次插入期间添加的文本进行换行。
