Thanks cmr I will do this.Also I received some feedback that "rust format file1.rs file2.rs .." would probably be better and I agree. |

Fix false positive on `semicolon_if_nothing_returned` Currently the [`semicolon_if_nothing_returned`](https://rust-lang.github.io/rust-clippy/master/index.html#semicolon_if_nothing_returned) lint fires in unwanted situations where a block only spans one line. An example of this was given in rust-lang#7324. This code: ```rust use std::mem::MaybeUninit; use std::ptr; fn main() { let mut s = MaybeUninit::<String>::uninit(); let _d = || unsafe { ptr::drop_in_place(s.as_mut_ptr()) }; } ``` yields the following clippy error: ``` error: consider adding a `;` to the last statement for consistent formatting --> src/main.rs:6:26 | 6 | let _d = || unsafe { ptr::drop_in_place(s.as_mut_ptr()) }; | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: add a `;` here: `ptr::drop_in_place(s.as_mut_ptr());` | = note: `-D clippy::semicolon-if-nothing-returned` implied by `-D clippy::pedantic` = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#semicolon_if_nothing_returned ``` I updated the lint to check if the statement is inside an `unsafe` block, a closure or a normal block and if the block only spans one line, in that case the lint is not emitted. This closes rust-lang#7324. changelog: enhanced semicolon if nothing returned according to rust-lang#7324.

Usage: rustc filename.rs --format
It formats the the specified file with --pretty normal.
There are two problems with this PR.
1.) I am using "process_output" instead of hooking me up in pretty_print directly. I didn't want to step on someones toes.
2.) Pretty print doesn't do a partial format. This mean that the source file doesn't get formated if the source code contains syntax errors.
I am currently using this with sublime. Every time I press ctrl+s it automatically saves and formats my current file.
