There are several tests.  First it detects whether stdout is attached to 
a windows console (Windows only of course).  If so, it uses console text 
attributes to do color.  If not, then it detects whether it is attached 
to an interactive terminal using the "isatty" function.  If so, it 
determines whether the terminal supports color by looking at the TERM 
environment variable.  This approach never prints color escapes when 
they are not supported, but may not always print color when it is supported.

We've now added "screen", "cygwin", and "rxvt-unicode".
