### autocomplete
Modifes how tab completion operates.

Usage: `autocomplete [dos | unix]`
<pre>
The default is to operate like the native platform. However
you can switch it between mode 'dos' and 'unix' as you prefer.
Options:
 dos	Each press of tab places the next option into the command line
 unix	Options are listed in a table, or put in-line if there is only one

Note: this command is only available on some versions of Windows
