Delete the old one first, then recreate it:
git push origin :139
git push origin 139
This is because tags are not meant to be updated, only to be added to --
other than branches, tags are meant as final,
create-once-and-never-update style, names. As such, even if you replace
a tag remotely, anyone who has already fetched it would need to
explicitly drop the tag locally and recreate it; git does not
auto-update tags that changed remotely.
In that light, it is probably better to just skip the 139 tag and move
on to 140.
