agentkeepalive on https?

[ianshward]

It looks like agentkeepalive is not used on HTTPS requests - this might be a relic from the past, when there was not support for HTTPS clients in agentkeepalive.

geojson-mapnikify/lib/get.js

Lines 58 to 59 in d40a0b4

	// Don't use keepalive agent for https.
	params.agent = uri.indexOf('https') === 0 ? null : agent;

This is just something I noticed when reviewing a recent PR, and therefore created this separate issue about it.
