More improvements to the `<python:trace>` code coverage report: * For files missing coverage, only take files into account that have a Python file name extension. * Previously, a `.pyc` file would have overwritten the coverage of a `.py` file, so it looked like the module had a coverage of 0 percent. * The line number of the `bitten.util.loc` module now starts at 0 to be consistent with the line numbering of files with coverage information.
