pullrequests/diff rest call returns incomplete JSON response

Summary

When accessing the diff for large pull requests via rest, the response can be truncated.

Steps to Reproduce

1. Access the pull request diff rest endpoint in a browser or using cURL - https://stash.company.com/rest/api/1.0/projects/PROJECT/repos/repo/pull-requests/1804/diff
2. Returned JSON data will be truncated

Expected Results

Returned JSON response is not truncated and can be parsed

Actual Results

JSON response is truncated.

In the browser, the response usually ends with:

"createdDate":1412767342465,"updatedDate":1412767404799,"comments":[],"attributes":{},"tasks":[],"permittedOperations":{"deletable":false,"editable":false}}

With cURL, it can end more abruptly:

...,"author":{"name":"user","emai

Workaround

If using curl, add --http1.0 to the command.
