Servo has a lot of comments like this: ```rust // https://example-spec.com/#do-the-thing fn do_the_thing() {} ``` and I keep turning these into doc comments whenever I'm working close to one of them. Doing so allows me to hover over a function call in an IDE and open its specification without having to jump to the function definition first. This change fixes all of these comments at once. This was done using `find components -name '*.rs' -exec perl -i -0777 -pe 's|^([ \t]*)// (https?://.*)\n\1(fn )|\1/// <$2>\n\1$3|mg' {} +`. Note that these comments should be doc comments even within trait `impl` blocks, because rustdoc will use them as fallback documentation when the method definition on the trait does not have documentation. Testing: Comments only, no testing required Preparation for https://github.com/servo/servo/pull/39552 --------- Signed-off-by: Simon Wülker <simon.wuelker@arcor.de>
