This applies to both the old and new URL rewrite paths, regardless of whether there's any rewriting going on.
Previously, a trailing slash after args would cause an extra arg to be added to the list with a value of '' (empty string). In the old logic, an embedded empty arg was illegal. That is: /a/c/f/arg1 gave args as ['arg1'] /a/c/f/arg1/ gave args as ['arg1', ''] /a/c/f/arg1//arg2 was illegal. Now, trailing slashes are stripped, so the first two examples about give ['arg1'], as does /a/c/f/arg1///// Also, embedded empty args are legal, so the arg2 example above yields ['', 'arg2']
