templatekw: force noprefix=False to insure diffstat consistency (issue4755) The result of diffstatdata should not depend on having noprefix set or not, as was reported in issue 4755. Forcing noprefix to false on call makes sure the parser receives the diff in the correct format and returns the proper result. Another way to fix this would have been to change the regular expressions in path.diffstatdata(), but that would have introduced many unecessary special cases.
