Disable autocomplete on Windows as default

[sfrieske]

Description

Autocompletion, which is on as default, causes reline to send a lot of ANSI chars which don't get interpreted by the Windows CMD shell. This is caused by reline and might ultimately be fixed there. Meanwhile, an easy fix is to set USE_AUTOCOMPLETE in IRB to false.
In order to not annoy people and make them enjoy IRB on Windows (may be with JRuby only?) please consider making this the default on Windows.

In the latest Reline, the same ANSI chars and rendering algorithm are used in both autocomplete mode and in noautocomplete mode.
So, this current state of the problem is one of these:

• Already fixed
• Not fixed even without autocompletion, maybe with multiline code input or when prompt line is at the bottom of the shell.

There is also a fix for windows in ruby/reline#775
Please open a new issue in ruby/reline if something is not working.
