The 'test -t 1' does not check the value of TERM.  It simply assumes a
vt220 terminal and assigns escape sequences without regard to terminal
type.  It really should only do this when there is a compatible $TERM
present.

The buildbot is effectively a 'script' session.  The output is a tty.
All of the output is saved to a file.  But TERM is not set.  It is a
dumb terminal.
