[PATCH] SVN Shell

Hello,

Please find attached the patch. The patch contains following fixes
(since they are trivial, i've combined them in one patch):

     1. Improve the output format of "ls" command.
     2. If no argument is passed to "setrev" command, set it to the
        youngest.
     3. Bug fix: Fix the exception when non-numeric data is passed as an
        argument to "setrev" command.
