Log test refactoring.
Log test refactoring.

* subversion/tests/cmdline/log_tests.py
  (parse_log_output): Set 'revision' field for items in the return
   value to a numeric value (as promised by the doc string), instead
   of a string representation of a numeric value.  Remove excess
   parenthesis around the value used in the assignment of local
   variable "lines".  Update extremely out-of-date TODO comment.

  (check_log_chain): Remove now-unnecessary use of int() around access
   to the 'revision' field of a log item.  Improve clarity of inline
   comment.
