The ColumnFormatter class will simplify output of column-oriented text for SSH commands like ls-groups and others (including HTTP counterparts) that may print user-supplied text that can contain tab and newline characters that would screw up scripts using these commands for automation. To deal with this, all text output is subject to C-style escaping of all non-printable characters. The escaping in done in the new StringUtil class. So far this new functionality is only used by the ls-projects command when the project description is printed. The escaping method used there previously only took care of newline characters.
