Unless the said invention carefully distinguishes a programming editor and a human language editor, the invention may still overlap on grounds of novelty. If the said invention does carefully distinguishes the two, the invention would still be questionable on grounds of obviousness unless it explains the key difficulties involved in migrating from programming languages to human languages and the invention claims a solution to that problem. I think the latter is unlikely.

Note: IANAL, and haven't read the claims of the said invention.
