Trying the vendor import of tzdata2020e

[Philip Paeps]

I am trying to test the vendor import of tzdata2020e but I am running 
into trouble:

(playground is gitrepo-dev.freebsd.org)

```
[658] {vendor/tzdata+1}(philip at rincewind)~/freebsd/tzdata% git push 
--follow-tags playground vendor/tzdata

```

Any idea what I'm doing wrong here?

Aside, while I was preparing the import, I discovered that I have a 
`GIT_AUTHOR_EMAIL` in my environment which Git will use in preference to 
the user.email setting in the repository.  Pointing this out here so 
someone searching the archives when debugging a similar problem has a 
breadcrumb.
