Sort order for file quickopen should prefer shorter paths

[spion]

I love VSCode, but the sort order for quickopen doesn't work all that well sometimes...

For example, shorter files within longer paths should not trump over shorter paths with a longer filename, especially if the search string includes a path separator

• VSCode Version: 1.8
• OS Version: OS X

Steps to Reproduce:

1. Create a file named config/test.js
2. Create a subfolder named config/test
3. Create the files config/test/t1.js and config/test/t2.js
4. Use quick open and type co/te

Expected first result: config/test.js
Actual first result: confing/test/t1.js. config/test.js comes only after t2

Minimal patch that demonstrates an improved behaviour:

diff --git a/src/vs/base/common/comparers.ts b/src/vs/base/common/comparers.ts
index a90bc8f..f0993ef 100644
--- a/src/vs/base/common/comparers.ts
+++ b/src/vs/base/common/comparers.ts
@@ -126,7 +126,7 @@ export function compareByScore<T>(elementA: T, elementB: T, accessor: IScorableR
        }

        // At this place, the scores are identical so we check for string lengths and favor shorter ones
-       if (labelA.length !== labelB.length) {
+       if (!/[\/]/.test(lookFor) && labelA.length !== labelB.length) {
                return labelA.length < labelB.length ? -1 : 1;
        }

but it looks like this is a generic label-and-path scoring algorithm, so I'm not sure if it will affect other things negatively?
