No, I didn't miss it; I saw your mention that it was copied from existing code in the script, but I assumed the existing code was recent -- hence my surprise. Since it's been around so long, I agree, it's hardly a cause for concern at this point (though, I still reflexively write the more portable notation as used by `OID_REGEX` and `_x05`, etc.).
