I'll write up a spec to ensure this functionality.

it is allowed according to the travis docs:
http://about.travis-ci.org/docs/user/build-configuration/#Set-environment-variables
```
You can specify more than one environment variable per item in the env array:

rvm:
  - 1.9.3
  - rbx-18mode
env:
  - FOO=foo BAR=bar
  - FOO=bar BAR=foo

```
