Patch applied in r42969. Since the  test coverage of src/pmc/codestring.pmc was already at 100%, we can be fairly confident that any problems caused by the patch will show up quickly. Patch passed make and make test on Linux/i386.

I'll hold ticket open for several days for comments and complaints.

Thank you very much.
