This reverts commit f525e1f383fc0d0a7adbdfb1bac6d6228ae79b33.
This removes color control from warnings for unstable features.
For some reason this removed color support from `cargo -Zhelp` in the
tests but I can't reproduce it locally.
The most important thing was getting the config fix in.
There are two follow ups
- Can we have the config working *and* color?
- Why did this fail for this field and not the others we already had
tests for?
I ran out my immediate time box for looking into these.
Fixes#13991
When merging configuration lists, the current order does not match
the expected precedence. This makes merged lists follow precedence
order, with higher precedence items merged later in lists.
Benefits:
- A TOML 1.0 compliant parser
- Unblock future work
- Have `cargo init` add the current crate to the workspace, rather
than error
- #5586: Upstream `cargo-add`
The `anyhow` crate interoperates with the `std::error::Error` trait
rather than a custom `Fail` trait, and this is the general trend of
error handling in Rust as well.
Note that this is mostly mechanical (sed) and intended to get the test
suite passing. As usual there's still more idiomatic cleanup that can
happen, but that's left to later commits.
