aa4cd311bb Add config options for spaces around the colon in struct literal fields 
In Rust, colons are used for three purposes:

* Type annotations, including type ascription
* Trait bounds
* Struct literal fields

This commit adds options for the last missing of the three purposes,
struct literal fields.

should just stop any regressions.

which is then a fixed-point.

abca1deded Add indent_match_arms option (#1404) 
Makes it optional whether to indent arms in match expressions. Setting this
to false may be desirable for people wishing to avoid double-indents, in
that if the match arm is a block, the block will cause an extra indentation
level, and if it isn't a block but just a single line, it's still easy to
see the logic at a glance.

This style is preferred in certain other languages with switch statements,
e.g. Linux style C and the most common Java style.

Make tests fail if rustfmt encounters an error 
Previously tests would not fail if they encountered an error such as
LineOverflow or TrailingWhitespace. Making the tests error out will fix
this mismatch between running rustfmt for real and running the tests.

This also modifies all tests that previously contained errors so that
they no longer contain errors (in almost all of the tests this is
accomplished by setting error_on_line_overflow = false).

Only change multiline comments of the form

```rust

```

while not affecting comments of the form

```rust
/*
Text
*/
```

when normalize_comments is off. In the first case,
we have a known character we can align against, while
we don't have one in the second case.

Before, we have converted the second form into the first,
but this is against the spirit of normalize_comments being
turned off.

61042e6e4d Fix issue 1124 - detect start of output rather than start of input file when writing output source file (#1133) 
* Change required to prevent a trailing space at the end of a separate module being propagated

* Detect the start of the output file rather than the start of the input file when deciding whether to output preceding snippets - this stops unnecessary whitespace and blank lines from being inserted when spans and statements are output in an order other than that from the input file.

* Add code to prevent space from being added with the prefix snippet if a) the snippet is entirely horizontal whitespace, or b) the snippet contains whitespace  followed by a newline. This prevents trailing spaces at the end of a line from being added.

* Tests for this issue

* Tidy up `match` statements

9fa5a91fc5 visitor: Handle specified line ranges in visit_stmt 
This commit adds a very rough implementation of handling the specified
line ranges in `config.file_lines_map` for statements. It reformats a
statement if its span is fully contained in the set of lines specified
for the file.

The implementation here is intended as a proof of concept, and
demonstration that the machinery added in the preceding commits is
functional. A final implementation would likely hook in via the
`Rewrite` trait.

The change to `format_visibiilty` means that `format_header` and
`format_unit_struct` can no longer fail. Their return type is updated to
reflect that.

9f98f725cb Detect when comments disappear 
When the reformatted code doesn't contain the same quantity of comments
as the original code, use the original code instead of the reformatted
code.
This is done for all expressions and `let` statements.

This should be used at the finest grained level possible, to avoid that
a small disappearing comment prevents a big chunk of code to be
reformatted.

Kind of fixes (avoid disappearing comments, but prevents a good
formatting is such case) #285 #225 #563 #743
