We see too often that a range-diff added to format-patch output shows too many "unmatched" patches. This is because the default value for creation-factor is set to a relatively low value. It may be justified for other uses (like you have a yet-to-be-sent new iteration of your series, and compare it against the 'seen' branch that has an older iteration, probably with the '--left-only' option, to pick out only your patches while ignoring the others) of "range-diff" command, but when the command is run as part of the format-patch, the user _knows_ and expects that the patches in the old and the new iterations roughly correspond to each other, so we can and should use a much higher default.
