$HOME environmental variable alteration in cmd/go/go_test.go

[m.hos...@gmail.com]

Hi,

Some of go tests in src/cmd/go was failing on my machine with SSL certificate problem. those test trying to do `go get` and `git clone`. After investigation I found out that in go_test.go file there is a line doing this:

os.Setenv("HOME", "/test-go-home-does-not-exist")

After commenting this line all the test passed without any problem since the `go get` command was able to locate .gitconfig in $HOME.

I just want to know what was the initial reason for changing the HOME in the first place? Am I missing something?

Thanks,
