Why do so few CLI tools use colour inside their error messages? For example, rustc uses colour well in the error display, but there's no special styling of the content in backticks. By contrast, markdown website almost always style backtick text differently from prose. E.g. `field` is not specially styled here.

TIL rustc has a style guide for suggestions! https://rustc-dev-guide.rust-lang.org/diagnostics.html#suggestion-style-guide They recommend avoiding 'did you mean' or 'the following' in favour of direct suggestions and highlighted positions.

I'm never sure what version of Rust to target for my projects. For difftastic I pinned to rust 1.57 and I haven't needed to bump it so far. Debian stable is still on 1.48 though!
