Exclude the bundled gem environment from being measured for code coverage.
Exclude the bundled gem environment from being measured for code coverage.

I'm not really all that interested (yet, anyway) in line coverage for
.bundle/environment.rb: it's only got ~62% line coverage, but it's
generated application support code that I never directly touch, so I'm
not yet particularly concerned about it so long as it works.

At some point, however, it might become an illuminating statistic.
