This is an interesting idea, but we need to think through what exactly
do we want: more use-cases, including the corner cases? Is there a
reference to what other regexp-accepting products do?

Your suggestion seems to amount to:
 1) Look for an explicit "^" at the beginning, add ".*" at the
beginning, otherwise.
 2) Look for an explicit "$" at the end, add ".*" at the end, otherwise.
