auto_complete_commit_on_tab should default to true

The docs state

// By default, auto complete will commit the current completion on enter.
// This setting can be used to make it complete on tab instead.
// Completing on tab is generally a superior option, as it removes
// ambiguity between committing the completion and inserting a newline.

If completing on tab is recognised to be "generally a superior option", which I couldn't agree more strongly with, why is the default enter? The autocomplete is an awesome and very powerful feature, however it does seem a little over enthusiastic and I had to google around to find out how to stop random things appearing at the ends of my lines - I'm sure other people will be doing the same.
