lgtm w/ fix.

https://codereview.chromium.org/1137683004/diff/1/.gitignore
File .gitignore (right):

https://codereview.chromium.org/1137683004/diff/1/.gitignore#newcode433
.gitignore:433: /webkit
nit: "webkit" sorts before "webpage" :).

Please add a comment above the line explaining why it exists/linking to bug.
e.g.

# Results directory for run-webkit-tests. http://crbug.com/488288
