…eykril fix: Highlight unlinked files consistently with inactive files Currently, rust-analyzer highlights the entire region when a `cfg` is inactive (e.g. `#[cfg(windows)]` on a Linux machine). However, unlinked files only highlight the first three characters of the file. This was introduced in rust-lang#8444, but users have repeatedly found themselves with no rust-analyzer support for a file and unsure why (see e.g. rust-lang#13226 and the intentionally prominent pop-up added in PR rust-lang#14366). (Anecdotally, we see this issue bite our users regularly, particularly people new to Rust.) Instead, highlight the entire inactive file, but mark it as all as unused. This allows users to hover and run the quickfix from any line. Whilst this is marginally more prominent, it's less invasive than a pop-up, and users do want to know why they're getting no rust-analyzer support in certain files. Before (note the subtle grey underline is only at the beginning of the first line):  After (user can hover and fix from any line):

This partially reverts rust-lang#17350, based on the feedback in rust-lang#17397. If we don't have an autofix, it's more annoying to highlight the whole line. This heuristic fixes the diagnostic overwhelming the user during startup.

Without this change, this piece of code throws a warning because
std::iois imported, and thenstd::io::stdinis used explicitly.From reading the paragraphs that follow that code, I assume that the original intent of the author was to show that code without the first line, the
useline. That way, the text seems to make better sense to me.
