examples/text_width.py only works with terminals wider than 135 chars

[redtoad]

When running examples/text_width.py inside terminals with 135 or less characters in width, the following error pops up:

Traceback (most recent call last):
  File "text_width.py", line 22, in <module>
    puts(columns([(colored.red('Column 1')), col], [(colored.green('Column Two')), None], [(colored.magenta('Column III')), col]))
  File "/tmp/clint/clint/textui/cols.py", line 95, in columns
    cols[_big_col][0] = max_width(cols[_big_col][0], cols[_big_col][1]).split('\n')
  File "/tmp/clint/clint/textui/formatters.py", line 70, in max_width
    chunks = schunk(word, (cols + offset))
  File "/tmp/clint/clint/utils.py", line 61, in schunk
    for char in string:
TypeError: 'ColoredString' object is not iterable

Thanks for this. Sorry I didn't see it before.

It actually appears that for this example, when you a terminal <120 it runs, but omits column II, so 120=>w<135 is the error zone. It's because that the example uses a column width of 60. Not sure the best way to handle it when columns is given column widths which in total are wider than the terminal.
