For this simplistic example, you can just strip common starting and 
trailling elements, and then ask if:

.* could match foo

Here the answer is yes. This simple technique falls apart for more complex 
examples though:

A = '^.*o.*$'
B = '^f.*o$'

Are still willing to match the same characters, but .*o.* does not 
obviously match f.*o in my simple world.

Herm. My brain hurts.
