Don't anchor search term for type to search keyboard layout

On the keyboard layout selection, one can simply type away his desired layout. A "find"-like dialog pops up with the input and the list is rolled to the first matching item (e.g. typing "slo" will match "slovenian").

I believe this would be nice if typing "bra" matched "portuguese (brazil)", but the search is hard-anchored so it is not matched. Better, in my opinion, would be to use \b{search term} in Perl or regex \<{search term} with GNU regex.
