commands.update() now works properly with a revision of 0

Without this change commands.update() treats an integer 0 as if no revision
was passed and updates to the branch head.  This fix allows an integer 0 to
be detected as a revision number so the working directory is correctly
changed to revision 0 rather than the branch head.
