Text is not extracted from links

[Unrud]

Description

Text is not extracted from links.

Environment

MDL Version
v0.11.0 and master

Expected Behavior

> <http://example.org> more text.

The example above doesn't violate the rule MD027 - Multiple spaces after blockquote symbol.

Actual Behavior

markdownlint thinks the example violates MD027.

Text from links is ignored:

markdownlint/lib/mdl/doc.rb

Lines 255 to 263 in 0b006db

	lines = element.children.map do |e|
	if e.type == :text
	e.value
	elsif %i{strong em p codespan}.include?(e.type)
	extract_text(e, prefix, restore_whitespace).join("\n")
	elsif e.type == :smart_quote
	quotes[e.value]
	end
	end.join.split("\n")

Just adding a to the list solves the problem for MD027 but causes issues with other rules because they rely on text from links being ignored (?).
