This sed replacement worries me.  I don't have a time to check myself
today but do we use \(this\|or\|that\) alternates with our sed script
already elsewhere in the codebase (test scripts do not count)?

Otherwise this may suddenly be breaking a platform that has an
implementation of sed that may be substandard but so far has been
sufficient to work with git.
