No longer using Go script's directory as current working directory

Several weeks ago, executing Go scripts would use the script's directory as the Current Working Directory, thereby ensuring that any data files were available. With the most recent version (3.8.1), the CWD has changed to GOPATH's src directory instead. As a result, it's looking for the data files in the wrong place.

Could the original behaviour be restored? Putting a specific project's data files in the src/ root is a bad idea (doesn't follow the GOPATH convention).

NOTE: I have no idea which version introduced this, because I don't know what version I was using before the upgrade, and I haven't found a way to downgrade packages.
