  Won't that be the case regardless of whether the build fails or succeeds?

  I think this patch is only really suitable for people who have 
something similar in their PS1. Otherwise it will just mess up your 
window title.

  Also, it should only be done if $TERM == xterm, otherwise you get 
annoying stuff when running buildroot from a text console. And in fact, 
the same is true of the colouring itself, so we don't get these annoying 
escape characters in log files and continuous integration web interfaces.

  Arnout
