What Johannes and I were discussing was the other number -- the
total in the series.  IOW, y in "[PATCH x/y]".  OTOH, the number
used for disambiguation you care about is x, which is made
adjustable with --start-number patch.

So the way for qgit to use it would become something like this.
Instead of giving a list of ranges like "a..b c..d e..f":

 * Run "format-patch a..b"; by reading from its stdout you know
   what patches you got -- you count them.

 * Run "format-patch --start-number=6 c..d" (if you got 5 out of
   a..b);

 * Run "format-patch --start-number=n e..f" (now you know the drill).

Then the sequence out of c..d would start with a file 0006-xxxx.txt,
which is what you want for disambiguation.
