无法解释的gq缩进问题

我将此文本插入Vim：

t tttt ttttttttt tt tttt tt ttt tttttt-tttt-ttttttt
tttttttttttttttttttttttttttttttttttttttttttttttttttttt ttttt ttt ttt tttttt
ttttttt tttt ttttttt: ttttttt tt ttttttt, ttttttt tt tttttt, tttttt tt ttttttt,
tttttt tt tttttt ttt. t tttttt tt ttt (tttt) ttttttt-tttttt-tt-ttttttt tttttt
for the "tttttt in ttttttt" part of the issue (in the previous week I have
worked on the "objects in objects" part). This part is about making it
possible for the end user to add arrays in objects. First of all I checked
that the current implementation allows putting arrays in objects at least
from the schema passed to the plugin constructor.

然后我在视觉上选择所有这些行并按gq。内容变为：

t tttt ttttttttt tt tttt tt ttt tttttt-tttt-ttttttt
tttttttttttttttttttttttttttttttttttttttttttttttttttttt ttttt ttt ttt tttttt
ttttttt tttt ttttttt: ttttttt tt ttttttt, ttttttt tt tttttt, tttttt tt ttttttt,
tttttt tt tttttt ttt. t tttttt tt ttt (tttt) ttttttt-tttttt-tt-ttttttt tttttt
for the "tttttt in ttttttt" part of the issue (in the previous week I have
    worked on the "objects in objects" part). This part is about making it
    possible for the end user to add arrays in objects. First of all I checked
    that the current implementation allows putting arrays in objects at least
    from the schema passed to the plugin constructor.

请向我解释为什么在最后四行的开头有空白。for在某些编程语言中，第五行的第一个单词（）是否会启动for循环，是否有可能使Vim认为它应启动一个新的缩进代码块，即使这些行位于未保存的文件或Markdown文件中？如何避免这种行为，并gq停止插入该空格？

我的comments设置具有默认值：s1:/*,mb:*,ex:*/,://,b:#,:%,:XCOMM,n:>,fb:-。你可以在这里看到我的.vimrc文件。

更新：我的fo（formatoptions）选项的值为tcq，formatexpr并且formatprg选项为空。

如果文件已保存/不是新文件，有什么不同吗？

— 加百利·彼得罗维

这是相同的行为。

然后，您可以从文本中删除该信息，以使问题更简单。

@GabrielPetrovay，谢谢您的反馈！:-)我更新了问题。

您的“ fo”选项和“ formatexpr”以及formatprg选项是什么？

— Christian Brabandt 2015年

问题是您已经设置好smartindent了~/.vimrc。这些smartindent选项使Vim缩进时假定您的文本是某种类似于C的编程语言。除其他外，它for像关键字一样对待，并在后面的行中增加了缩进级别。看到
