What's "best matches"? I suggested using `tag-exact-match-p' in the 
etags backend. What's your take on this?

Without using the order, in which matches are returned by the backend, 
we can't even know what the "best matches" are.

What about the rest of the predicates in `find-tag-tag-order' set by 
`etags-recognize-tags-table'? Should we disregard all of them?
