为什么 GitHub 不喜欢 % 字符？
Why doesn't GitHub like the % character?
我有一个包含多个 C 源文件的 GitHub 存储库。 （除非绝对必要，否则我不会分享 link，这样我就不会被指责为做广告。）C 文件中 % 字符的每个实例都以红色突出显示:
我是否在 C 语言中遗漏了一些有关 % 的内容，这是一个错误，还是故意的？
我发现 this discussion 有一个合理的解释。这里我引用：
It's highlighting the % because it's assuming that you're making a printf format string, and that you've made it wrong. Unfortunately there's no way to tell it it's not a printf format string short of changing the syntax file.
GitHub 使用 linguist 来检测语言，可以在那里找到一些突出显示的问题（即使它不直接涉及语言检测模块）
参见 issue 2839 其中确实提到了
We use open source TextMate-style language grammars for syntax highlighting, which are available here:
https://github.com/github/linguist/blob/master/grammars.yml
Linguist pulls in grammar updates with each new release, which usually happens every couple of weeks.
对于 C，是 textmate/c.tmbundle, which had a percent-related highlighting issue before (issue 28)：您可能需要在那里打开一个新问题。
