Regression in auto-completion - word ordering

Autocomplete now does some trick to allow out of order terms to be completed.
eg.

The first item shows up as...
RNA_e --> RNA_api_environment_map

And not...
RNA_e --> RNA_exit

Such features are fine and for some API's I can see it could be handy
especially if you have trouble remembering word order.

But I've found myself having to use arrow keys to select the correct
term when it would have been selected immediately before this feature
was added.
