The logic behind preventing multiple form parameters with same name.

return nil, fmt.Errorf("Must have exactly one value per param")

I am creating an application that makes authorized request to following endpoint.
https://www.etsy.com/developers/documentation/reference/listinginventory

The endpoint expects multiple price_on_property field as form parameter. The library blocking this usage type. It blocks my project at the same time :). If there is no plausible reason to prevent this better to make pull request to change the behaviour.

Indeed, you're right!

http://oauth.net/core/1.0a/#anchor13 says:

Parameters are sorted by name, using lexicographical byte value ordering. If two or more parameters share the same name, they are sorted by their value.

So we should support multiple parameters with the same name.

I'm busy with a new baby, and can't promise to implement this right away. I'll try to make some time for it, but, feel free to send a PR if you need it sooner.

I hope I don't make some bugs inside.

If two or more parameters share the same name, they are sorted by their value.

It seems like the parameters are not sorted by values
