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.
