archive: support 'wdir()'

This is a step toward replacing the extdiff internals with archive, in order to
support 'extdiff -S'.  Only Mercurial subrepos are supported for now.

If a file is missing from the filesystem, it is silently skipped.  Perhaps it
should warn, but it cannot abort when working with extdiff because deleting a
file is a legitimate diff.

import os

if os.environ.get('COVERAGE_PROCESS_START'):
    try:
        import coverage
        import random

        # uuid is better, but not available in Python 2.4.
        covpath = os.path.join(os.environ['COVERAGE_DIR'],
                               'cov.%s' % random.randrange(0, 1000000000000))
        cov = coverage.coverage(data_file=covpath, auto_data=True)
        cov._warn_no_data = False
        cov._warn_unimported_source = False
        cov.start()
