fix issue

If you have text like (test (test (test))) with your cursor on the left-most closing paren, typing vib does nothing while vi) makes the region go over the inside of the inner-most parentheses. This fixes it so they behave the same. Specifically, it relaxes the rule that the new region must properly contain the old region to when there actually is a region -- IE (point) can be outside of the new region.

I don't plan to do any further work on this package (targets.el will implement all of this package's functionality). I have a note in the title information, but I will also add a deprecation notice to the readme.
