222bac1397 Provide config.set().item(value) API. 
This API isn't fantastic, but it's the best I can come up with without
something like `concat_idents!()`. There are relatively few places where
config is set, to hopefully the ugliness isn't disastrous.

Change previous occurences of `config.item = value` to this new API,
rather than using `config.override_value()`. Undo the changes to
`override_value()`, as it's no longer important to propogate the error
to the caller. Add a test for the new interface.

dcd3c0ed2e Add test for issue #1366. 
As the comments in the issue state: it appears to work now, so this test
should just stop any regressions.

The second example in the issue description will format to the first,
which is then a fixed-point.

c0bdbfa531 Switch to accessing config items via method. 
Preparation for #865, which proposes adding a flag which outputs which
config options are used during formatting.

This PR should not make any difference to functionality. A lot of this
was search-and-replace.

Some areas worthy of review/discussion:

 - The method for each config item returns a clone of the underlying
   value. We can't simply return an immutable reference, as lots of
   places in the code expect to be able to pass the returned value as
   `bool` (not `&bool). It would be nice if the `bool` items could
   return a copy, but the more complex types a borrowed reference... but
   unfortunately, I couldn't get the macro to do this.
 - A few places (mostly tests and `src/bin/rustfmt.rs`) were overriding
   config items by modifying the fields of the `Config` struct directly.
   They now use the existing `override_value()` method, which has been
   modified to return a `Result` for use by `src/bin/rustfmt.rs`. This
   benefits of this are that the complex `file_lines` and `write_mode`
   strings are now parsed in one place (`Config.override_value`) instead
   of multiple. The disadvantages are that it moves the compile-time
   checks for config names to become run-time checks.

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.

f96e56c3a0 Avoid extra comma in vertical single-field struct patterns (#1403) 
* Add (failing) test for #1397

* Fix for #1397

Specifically, we end up double-adding a trailing comma for single-member
struct patterns that are arranged vertically. One is added by write_list
(since such structs return true for needs_trailing_separator), and
another is added by the if in the old code.

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).

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.

* 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

* Add test with blank lines between `use` statements

5361f61110 Include git commit and worktree status in version output (#1060) 
This will help in debugging issues as rustfmt gets more users.

If the working tree is clean, output looks like

    $ target/debug/rustfmt -V
    0.5.0 (9f5ed3b)

If the working tree is dirty, output looks like

    $ target/debug/rustfmt -V
    0.5.0 (9f5ed3b worktree dirty)

If git is unavailable, output looks like

    $ target/debug/rustfmt -V
    0.5.0 (git commit unavailable)

To avoid rebuilds on changing tests, the build script will only rerun if
files under src/ are changed. This means the actual git status may show
changed files and this would not show up in the version. This should not
be an issue as files not in src/ should not affect the build output.

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.

882ef8cc82 Fix off by 2 error in function sigs 
Fixes #1000

This is a little conservative in some cases, but better than being wrong in others.

9b05461666 Write each file as it is formatted (#991) 
The old behaviour stored everything in memory until we were finished. Now we write as soon as we can.

This gives better behaviour when formatting large programs, since there is some progress indication. It also opens the door to optimising memory use by not storing everything in memory unless it is required (which it still might be). That is left as future work though.

96d59366fc Don't misplace the :: on associated items. 
The rewritten location of the :: on global paths for qpaths was wrong.
