f0fe9c3c4a chains: prefer to use the next line for an expression, if using the same line would introduce an open block or similar 
This problem came to light due to the chains changes, but effects other code too. It only happens rarely, e.g.,

before this fix:
```
    match foo {
        MacroArgKind::Delimited(ref delim_tok, ref args) => rewrite_delimited_inner(
            delim_tok,
            args,
        ).map(|(lhs, inner, rhs)| format!("{}{}{}", lhs, inner, rhs)),
    };

```

after:
```
    match foo {
        MacroArgKind::Delimited(ref delim_tok, ref args) => {
            rewrite_delimited_inner(delim_tok, args)
                .map(|(lhs, inner, rhs)| format!("{}{}{}", lhs, inner, rhs))
        }
    }

```

5bc27593f4 chains: minor fixups 
* remove unnecessary clone
* comment formatting
* fix bug with `?` collection
* respect the heuristic if the root is more than just the parent

a8d5f25572 chains: split handling of chains in block and visual cases 
Just refactoring, lots of code dup here, but it should get better...

728b0182c5 Changes to chains with block indent 
* More often combine a chain item to the previous line (if it is a block)
* Don't indent if the parent is a block

This is not perfect and doesn't pass tests, but I need to refactor to make more
progress

a41947cd7d Enable doctests 
Doctests were disabled globally because up until #2456, they were just
formatting examples which were not supposed to compile. Now that there
is one runnable doctest, I disabled the other ones individually (by
adding the ignore directive).

I also added some empty lines around the code blocks to avoid the
following warning and instead ignore the code blocks cleanly:

WARNING: ... Code block is not currently run as a test, but will in
future versions of rustdoc. Please ensure this code block is a runnable
test, or use the `ignore` directive.

See rust-lang/rust#28712 for further details.
