This is a [breaking-change] for syntax extension authors. The fix is to use MultiModifier or MultiDecorator, which have the same functionality but are more flexible. Users of syntax extensions are unaffected.
Currently, `early_error` and `early_warn` in `librustc::session` always use `ColorConfig::Auto`. Modify them to follow the color configuration set by the `--color` option.
As colored output is also printed during the early stage, parsing the `--color` option should be done as early as possible. However, there are still some cases when the output needs to be colored before knowing the exact color settings. In these cases, it will be defaulted to `ColorConfig::Auto`, which is the same as before.
Fixes#27879.
It is very difficult to find tidy problems in the midst of the output of
the LLVM/jemalloc/etc. build, and travis is great for the former, so
lets remove that problem.

Encountered an issue with `pacman` while going through the guide for installing the `mingw` toolchain on Windows with `msys2`, after some googling I found the [solution](https://github.com/Alexpux/MSYS2-packages/issues/163#issuecomment-73555971).
I thought it would be good to update the README so people don't get frustrated. 😃

After submitting #28031, I ran a [script](https://gist.github.com/durka/a5243440697c780f669b) on the rest of src/ and found some anomalies. In this PR are the fixes that I thought were obvious (but I might be wrong!). The others I've submitted in issue #28037.
If you have an `Iterator<Item=String>` (say because those items were generated using `.to_string()` or similarly), borrow semantics do not permit you map that to an `Iterator<&'a str>`. These two implementations close a small gap in the `String` API.
At the same time I've also made the names of the parameters to `String`'s `Extend` and `FromIterator` implementations consistent.
We were using them for every expansion, instead of using `Name`.
Also converted `CompilerExpansion` into an enum so its nicer to use and takes up less space.
Will profile later, but this should be a small improvement in memory usage.
