New options:

 -<columns> insert conditional-newlines to force wrap (e.g. -80)
 -newline   append a newline (CRLF) sequence to the output filea

The -<columns> option allows you to take "80-column ANSIs", artwork which
uses 80 columns and assumes the cursor will wrap to the next line
automatically, and insert Ctrl-A/ (conditional-newline) which allows the
file to be viewed nicely on wider terminals. Very cool.

Also added -newline (which can be used multiple times) to append one
(or more) newline sequences to the output file.

Use uppercase for Ctrl-AN and Ctrl-AL when -clear is used.
