title: Rails console initiates a "Display all 573 possibilities? (y or n)" dialog when I paste a multiline instruction into it
body: <p>I am copying the following snippet from my text-editor to my rails console:</p>
  
  <pre><code>request = Typhoeus::Request.new(
  "https://track.customer.io/api/v1/customers/4", 
  ssl_verifypeer: false,
  method: :put,
  headers: {
      "Content-Type" =&gt; "application/json",
      "User-Agent" =&gt; "#{Rails.configuration.customerio[:site_id]}:#{Rails.configuration.customerio[:api_key]}"},
  body: '{
  "email":"first@last.com", 
  "name":"Name is here",
  "id":"4",
  "created_at":"#{Time.now}"}')
  </code></pre>
  
  <p>When I copy it all as one line:</p>
  
  <pre><code>request = Typhoeus::Request.new("https://track.customer.io/api/v1/customers/4", ssl_verifypeer: false,method: :put,headers: {"Content-Type" =&gt; "application/json","User-Agent" =&gt; "#{Rails.configuration.customerio[:site_id]}:#{Rails.configuration.customerio[:api_key]}"},body: '{"email":"first@last.com", "name":"Name is here","id":"4","created_at":"#{Time.now}"}')
  </code></pre>
  
  <p>Then console returns with a standard response:</p>
  
  <pre><code> =&gt; #&lt;Typhoeus::Request:0x00000101c517a8 @base_url="https://track.customer.io/api/v1/customers/4", @original_options=...
  </code></pre>
  
  <p>However, if I copy it line-by-line (as I did in the first code snippet) I get a strange error.  The console asks me if I want to display all possibilities, as if I'm searching a directory or making a search query midway through the paste.  Check it out:</p>
  
  <pre><code>1.9.3p393 :091 &gt; request = Typhoeus::Request.new(
  1.9.3p393 :092 &gt;     "https://track.customer.io/api/v1/customers/4", 
  1.9.3p393 :093 &gt;     ssl_verifypeer: false,
  1.9.3p393 :094 &gt;     method: :put,
  1.9.3p393 :095 &gt;     headers: {
  1.9.3p393 :096 &gt;
  Display all 573 possibilities? (y or n) 
  1.9.3p393 :096 &gt;       "Content-Type" =&gt; "application/json",
  1.9.3p393 :097 &gt;
  Display all 573 possibilities? (y or n) 
  1.9.3p393 :097 &gt;       "User-Agent" =&gt; "#{Rails.configuration.customerio[:site_id]}:#{Rails.configuration.customerio[:api_key]}"},
  1.9.3p393 :098 &gt;     body: '{
  1.9.3p393 :099'&gt; "email":"first@last.com", 
  1.9.3p393 :100'&gt; "name":"Name is here",
  1.9.3p393 :101'&gt; "id":"4",
  1.9.3p393 :102'&gt; "created_at":"#{Time.now}"}')
  </code></pre>
  
  <p>If I select <code>n</code> both times, the request is created normally.  However, if I select <code>y</code>, it lists 573 items, most of which I've put into this pastie: <a href="http://pastie.org/private/ksgzqhd50mvdi0t6cqe8g" rel="noreferrer">http://pastie.org/private/ksgzqhd50mvdi0t6cqe8g</a></p>
  
  <p>Do you know what these results are and, more importantly, why they're being prompted at this strange time?</p>
