Or alternatively, take the escape sequence out of PROMPT and "echo -n" it
from inside the precmd() function ... here is my version:

PROMPT='%? //%n@%B%m%b%//
%l%1v%!> '
RPROMPT='(%T, %w)'
function precmd {
 echo -n "^[]0;//$USER@$HOSTNAME$PWD/ ($UNAME)^G"
 }

The advantage of this is that it doesn't mess up non-xterm terminals so
much (where the escape sequence will not be recognised and thus _will_
shift the cursor). PROMPT will overwrite the "echo -n"ed line whether it
is printed or not (so long as it is less than 80 chars).
