Bug #9949: Net::FTP#gettextfile truncates last line when missing newline before EOF
https://bugs.ruby-lang.org/issues/9949#change-47256

* Target version: 
* ruby -v: ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-linux]

----------------------------------------
Capturing a file from FTP using the default ftp.get (assuming binary is false) causes text files to get truncated before the last occurrence of "\n". This means that files missing a newline before EOF are corrupted.

~~~
Net::FTP.open(host, username, password) do |ftp|
  puts ftp.gettextfile(filename, nil)
end
~~~

Tested with "\n" in different positions to characterize the incorrect behaviour:

~~~
file: "<xml></xml>"   output: ""
file: "<xml>\n</xml>" output: "<xml>"
file: "<xml></xml>\n" output: "<xml></xml>"
~~~

Behaviour looks correct in 1.9.3, returns full file content in all cases. Regression exists in ruby 2.0 and 2.1. Tested with:

ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]
