Hmm, I can't apply this patch:

patch unexpectedly ends in middle of line
patch: **** Only garbage was found in the patch input.

It does look wonky, see import Common. following @@@ at line 5.

Fixed. I was using git show and I thought it produces a proper patch.

It was easy enough to apply by hand :) Also, it would not apply cleanly to the tip of 0.13 branch as of today. I'll fork sbt repo and push the change shortly.
