Document that CStr::as_ptr returns a type alias Rustdoc resolves type aliases too eagerly rust-lang#15823 which makes the [std re-export](https://doc.rust-lang.org/stable/std/ffi/struct.CStr.html#method.as_ptr) of `CStr::as_ptr` show `i8` instead of `c_char`. To work around this I've added info about `c_char` in the method's description. BTW, I've also added a comment to what-not-to-do example in case someone copypasted it without reading the surrounding text.
…ut, r=jyn514 Improve building compiler artifacts output Fixes rust-lang#108051 ``@Manishearth,`` ``@jyn514`` mentioned you might be interested in these changes to the outputs.
…tein-distance, r=tmiasko Use restricted Damerau-Levenshtein distance for diagnostics This replaces the existing Levenshtein algorithm with the Damerau-Levenshtein algorithm. This means that "ab" to "ba" is one change (a transposition) instead of two (a deletion and insertion). More specifically, this is a _restricted_ implementation, in that "ca" to "abc" cannot be performed as "ca" → "ac" → "abc", as there is an insertion in the middle of a transposition. I believe that errors like that are sufficiently rare that it's not worth taking into account. This was first brought up [on IRLO](https://internals.rust-lang.org/t/18227) when it was noticed that the diagnostic for `prinltn!` (transposed L and T) was `print!` and not `println!`. Only a single existing UI test was effected, with the result being an objective improvement. ~~I have left the method name and various other references to the Levenshtein algorithm untouched, as the exact manner in which the edit distance is calculated should not be relevant to the caller.~~ r? ``@estebank`` ``@rustbot`` label +A-diagnostics +C-enhancement
