"New relationship" contact autocomplete returns search results that are too long

See a screencast of this bug: http://screenr.com/gQ2

The "New relationship" form (e.g. /civicrm/contact/view/rel?cid=346&action=add&reset=1) populates the "Find Target Contact" search box with the results of the autocomplete selection. However, it doesn't choose the selected contact. It just places the contact's name in the search box. Since we have a number of contact organizations with names starting with "University of", the search results list ends up being too long.

Better behavior would be to actually select the item from the autocomplete list (and skip the search altogether) or to put the selected contact's name in quotes so that the search only returns that matching item (or a very limited number of results).
