Not the exit code but the number of the tty.  In an X11 terminal 
session, it's only a number, because those are pseudo-terminal slaves.  
In character mode sessions, it prints e.g. "tty1".

That's why I have the $PS1 split out over two lines.  That way, I can 
always see the full path without that it consumes screen space I could 
use for typing commands. :-)

I also have a newline ("\") at the beginning of the $PS1, so that 
there's always a blank line between the output of the last command and 
the prompt, which makes it easier for me to read.
