data info confusing error code

[Branko-Dj]

When running example command from README.md
data info http://datahub.io/core/gold-prices
we get the following error:

Error! Protocol "https:" not supported. Expected "http:"

When we run the command with "https:" no error is reported. So I'm guessing the command should look like this data info https://datahub.io/core/gold-prices and error would say:

Error! Protocol "http:" not supported. Expected "https:"
