--index-url not parsed correctly

[bennati]

Analyzing a requirements.txt file that contains -i URL or --index-url URL fails with the error below.
This was tested with 0.12.1 and 0.10.0, the parsing happens correctly in version 0.10.0.
Replacing -i with --extra-index-url solves the issue.

Error:

Looks like a duplicate of #173.
