And newer version of Git _will_ try to improve how patch text appears to be more useful to human users, so you have more moving parts than you'd want to even think about enumerating. If you were to add a new e-mail header, wouldn't it make more sense to add a patch-id header and agree on the set of options to be used to generate that patch-id (which might be different from the setting used to format the real patch for human and "git am" consumption)?
