Documentation: inline code isn't formatted inside lists

[pravic]

For example, in https://doc.rust-lang.org/nightly/std/option/enum.Option.html#method.filter code blocks look like plain text even if they are marked as code in source.

Those formattings are specified under the CSS selector .docblock p>code, .docblock-short p>code" which doesn't cover the ul li case.

Indeed! I'll write a fix this evening.
