Thanks for the precise recipe.  I installed zsh 5.0.0 from ports in
FreeBSD 9 and tried it, but I can't reproduce the bogus red colouring
(with the rewritten ansi-color-apply-sequence).

So I would like to ask you to do some more investigation:

As usual, load ansi-color and then eval the new definition of
ansi-color-apply-sequence.

Then

M-x trace-function-background <return> ansi-color-apply-sequence <return> 
<return>
M-x trace-function-background <return> comint-output-filter <return> <return>

M-x shell and type in the same shell commands as above.

M-x untrace-all

Then please attach the content of "*trace-output*" to your reply.

Wolfgang
