git-format-patch --start-number <n>

Since the "a..b c..d" syntax is interpreted as "b ^a d ^c" as other
range-ish commands, if you want to format a..b and then c..d and end
up with files consecutively numbered, the second run needs to be able
to tell the command what number to start from.

This does not imply --numbered (which gives [PATCH n/m] to the subject).
