The terminal module now also checks if the terminal actually is a terminal. 

The output is now limited to 80 characters; this is useful when cat'ing to a
file and terminal.get_size() is called. The previous behaviour was to always
output according to the terminal width, something that probably isn't what
someone usually wants when outputting to a file.
