convert/svn: fix _iterfiles() output in root dir case (issue2647) When converting directory additions/replacement with project directory set to root, _iterfiles() sometimes returned paths starting with a slash making following svn calls to fail. I could not reproduce the issue with hand-crafted repositories. Report and first analysis by Clinton Chau <clinton@clearcanvas.ca>

try:
    import coverage
    if hasattr(coverage, 'process_startup'):
        coverage.process_startup()
except ImportError:
    pass
