Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
stupid: Fail over to full revision when a PatchError is thrown (issue294) Also give an enhanced exception message when an AssertionError is thrown out of subvertpy. Can't test this as throwing an exception from the appropriate place leaves file handles open in the SVN repository, resulting in a failure to clean up in tearDown().
