example of environment variables seems incorrect

[jaraco]

In the config spec, it states:

Example of valid environment variables:

    bower_https_proxy is evaluated as https-proxy
    bower_storage__cache is evaluated as storage.cache

But in the description of storage, the only valid keys are packages, registry, and link with no mention of cache. This confusion example also appears on the docs for config.

Am I right in thinking these examples should be updated to match the valid keys? Am I also right in thinking that one needs to override all three if ~/.bower is not available?

Hello.
The doc has been updated with packages. You do can override all three:
