@ianlancetaylor requested issue #35314 to be considered for backport to the next 1.13 minor release.

I have no idea.

@gopherbot Please open backport issues

[release-branch.go1.13] os/exec: use environment variables for user t…
6fcea1e 
…oken when present

Builds upon the changes from #32000 which supported sourcing environment
variables for a new process from the environment of a Windows user token
when supplied.

But due to the logic of os/exec, the Env field of a process was
always non-nil when it reached that change.

This change moves the logic up to os/exec, specifically when
os.ProcAttr is being built for the os.StartProcess call, this
ensures that if a user token has been supplied and no Env slice has
been provided on the command it will be sourced from the user's
environment.

If no token is provided, or the program is compiled for any other
platform than Windows, the default environment will be sourced from
syscall.Environ().

For #35314
Fixes #37433
