A small test file will demonstrate this problem:
$ cat test.sh
#!/usr/bin/env bash
echo -e "\E[31mRed \E[32mGreen"
When running this, I expect to get "Red" in red and "Green" in green.
Running `emacs -Q --eval '(ansi-term "./test.sh")' with Emacs 24 results
in "Red" in black (not red as expected) and "Green" in green. Doing this
with Emacs 23.1 results in the expected behavior ("Red" in red).

The issue first appears in 23.2. Removing the call to term-ansi-reset in
term-mode brings back the red.

More specifically, this seems to fix your problem.
I haven't checked yet if it has other consequences though:

Stefan, you have some comments in term.el saying that
term-ansi-face-already-done should perhaps be t in more places.
Maybe this example shows why it shouldn't be?

I can't remember any of it and don't have time to look into it now,
so... I'll trust you on that, but in any case, it suggest complementing
my comment.
Stefan

I'm afraid I know nothing about what is going on here, I just saw by
experiment that reverting that change fixed the reported issue.
I committed it so it will hopefully get some testing that may reveal
whether or not there are any other consequences.
