getpapers should not urlencode '&', '=', or '?' in its query URLs

[sedimentation-fault]

Problem

In getpapers/lib/arxiv.js we see:

var queryurl = arxiv.baseurl + encodeURIComponent(query)

Using encodeURIComponent is overkill here, it will 'urlencode' all characters of query, including '&', '?' and others. According to my understanding of the HTTP protocol, this is even plain wrong.

Solution

Use encodeURI instead:

var queryurl = arxiv.baseurl + encodeURI(query)
