Only set mode of new patch if the target file was removed before.
If the file is writable by the user, but owned by a different user, the
chmod will otherwise fail with "Operation not permitted".
Additionally make very sure that the file is only written if either the number
of links is <= 1 or the file was successfully removed.
Maybe this minimal COW code should be replaced by something from util.

tests: tidy up reporting of skipped tests
if not verbose:
- print 's' rather than '.'
- pass skipped test reports back to parent for -j
- report which tests were skipped at the end
- print '.' after test completion
Allow explicit disabling of extensions
If the first character of an extension path is '!', the extension
is silently skipped.
