I'd try to take reasonable precautions, maybe cloud things a little.
I used to "post like a Canadian" sometimes -- include little references to Ottawa or poutine or whatever, throw in a few OUs... looks like you could do the opposite and be careful to write more "American" on your next project.
Also if you really want to go insane, start looking into styleometry, then styleometry as applied to code, here's two good starting points:

Just small things, like writing a script that swaps tabs for spaces, single quotes for double quotes... anything that automates changing some very human part of your writing style, similar to how a handwritten note often has specific ways people cross a T or dot an i, will get you far, since your adversary will probably not assume you've been clouding your data since the 2000s or whatever.
