From: ZheNing Hu <adlternative@xxxxxxxxx>
Usually we can only use `format-patch -v<n>` to generate integral
version numbers patches, but sometimes a same fixup should be
labeled as a non-integral version like `v1.1`, so teach `format-patch`
to allow a non-integral version which may be helpful to send those
patches.
`<n>` can be any string, such as `-v1.1`. In the case where it
is a non-integral value, the "Range-diff" and "Interdiff"
headers will not include the previous version.

[GSOC] format-patch: allow a non-integral version numbers
There is a small question: in the case of --reroll-count=<n>, "n" is an
integer, we output "n-1" in the patch instead of "m" specified by
--previous-count=<m>,Should we switch the priority of these two: let "m"
output?
this want to fix #882 Thanks.
