- GOTO command: Add a lower-bound test when skipping trailing spaces and such. - CD/CHDIR command: Fix the helper SetRootPath function so that it fails if getting the full path string fails, and remove trailing whitespace from directory string. Fixes stuff like: cd .. && echo success cd ".. " && echo success etc... CORE-6810 svn path=/trunk/; revision=67020
