Fix path calculation and revision specification for hgsubversion client.
Review Request #3326 — Created Sept. 12, 2012 and submitted
1. Fix calculation of base_path and path. Previous calculations would strip the username field from the repository and then use the length of that to calculate the base_path: svn://email@example.com/repo => svn://test.com/repo svn://firstname.lastname@example.org/repo/trunk base_path would then be calculated as ".com/repo/trunk" instead of "/trunk". 2. Allow users to specify a revision to diff against when posting reviews.
Two tests added, all previous tests pass.
