The documented behavior of --color=auto is this:
* auto - Only use color if standard output is a terminal.
This is designed so that an alias of ls='ls --color=auto' can be used
with pipes. That is, "ls | grep foo" would expand because of the
alias to "ls --color=auto | grep foo" won't output color codes because
the output in that case will be a pipe and not a tty.

I don't understand. That snippet you show works perfectly for me. I
am also an emacs user and the above configures perfectly for me within
an emacs shell. Therefore I don't understand what problem you are
reporting. Does the above not configure things for you properly? Is
there a problem with it?

Please clarify as to what the problem is that you are experiencing. I
don't see a bug here yet.
Thanks
