Fixed handling of filter regexps.

[psii]

Regexps in RUST_LOG as explained in the module documentation should
only allow log messages that match the given expression and not the
other way around.

Can you be sure to add a test for this as well? It seems odd that this wasn't tested before...

I attempted to write a test case before submitting this pull request, but I
didn't see a straightforward way to do this. Some restructuring of the code
is necessary. I can look for a solution but it will take some time.

One way to do this is to add an integration test under tests/foo.rs, disable the test harness, and then have the test re-execute itself with an environment variable set. That way it can test the stdout/stderr.

Added a test case which is implemented like you suggested.

Thanks!
