Fix mispositioned error indicators Fixes #38384 Most of the Rust community uses 4 spaces for indentation, but there are also tab users of Rust (including myself!). This patch fixes a bug in error printing which mispositions error indicators when near code with tabs. The code attempted to fix the issue by replacing spaces with tabs, but it sadly wasn't enough, as sometimes you may not print spaces but _ or ^ instead. This patch employs the reverse strategy: it replaces each tab with a space, so that the number of _ and ^ and spaces in error indicators below the code snippet line up perfectly. In a study [1] preceeding this patch, we could see that this strategy is also chosen by gcc version 6.3.0. Its not perfect, as the output is not beautiful, but its the easiest to implement. If anyone wants to improve on this, be my guest! This patch is meant as improvement of the status quo, not as perfect end status. It fixes the actual issue of mispositioning error indicators.

LL | let some_vec = vec!["hi"];
pretty: trim paths of unique symbols If a symbol name can only be imported from one place for a type, and as long as it was not glob-imported anywhere in the current crate, we can trim its printed path and print only the name. This has wide implications on error messages with types, for example, shortening `std::vec::Vec` to just `Vec`, as long as there is no other `Vec` importable anywhere. This adds a new '-Z trim-diagnostic-paths=false' option to control this feature. On the good path, with no diagnosis printed, we should try to avoid issuing this query, so we need to prevent trimmed_def_paths query on several cases. This change also relies on a previous commit that differentiates between `Debug` and `Display` on various rustc types, where the latter is trimmed and presented to the user and the former is not.

Explain move errors that occur due to method calls involving `self` This is a re-attempt of #72389 (which was reverted in #73594) Instead of using `ExpnKind::Desugaring` to represent operators, this PR checks the lang item directly.

note: `into_iter` takes ownership of the receiver `self`, which moves `some_vec`

help: you can `clone` the value and consume it, but this might not be your desired behavior
