Ah. I'm a "less" kind of a person, and less doesn't let escape codes
through by default, so this didn't occur to me.

There Is More Than One Way To Do It. (That's the perl mantra,
actually, but you get the idea.) Anyway, here are two ideas:

bash or zsh shell function:
function ml {
   ls --color=yes $* | more   
}

tcsh alias:
alias ml 'ls --color=yes \!* | more'

Bourne shell script:
$ cat > ~/bin/ml
#! /bin/sh
exec ls --color=yes $* | more
^D

They basically do the same thing, except that you can't use the tcsh
alias version of ml within other macros and the shell script version
is available no matter what shell you are using.
