Specifies a maximum line length to be used in the line
wrapping process. By default the message to be output is split
into chunks of no more than the maximum line length, and each
chunk is written on a new line. The split is made at word
boundaries if possible.
The default maximum line length is 79 characters.
If VALUE is set to 0, no wrapping will occur. If it is
set greater than 6, it specifies the maximum output line length.
Note that the minimum VALUE is 7, to allow for exclamation marks
and indentation.
