You're right.  Old habits die hard.  But: `emacs' itself also sets
those variables.

        default-process-coding-system's value is
        (iso-latin-1-dos . iso-latin-1-dos)

and

        process-coding-system-alist's value is nil

I'm 99% sure it is indeed related to CR characters; I think `od' shows
\r in the output of `echo' because they were passed as *input* to
`echo'.

Here's another experiment I did that will convince you (at least, it
convinced me):  I typed

        ls RET

, three keystrokes, into the buffer, and saw (as I described before)

        : command not found

... precisely what I see if, on a GNU/Linux system (also Emacs 21.2,
bash 2.05a.0, same .emacs.el file) I type

        ls C-q C-v C-q C-m

(control-V is the shell's "quote-the-next-character" character)

So Bash on Win32 is behaving precisely as Bash on GNU/Linux behaves,
if I quote the carriage-return.

Similarly, if I type

        ls SPC RET

to Win32 Emacs, I see

        : No such file or directory

... precisely what I see on GNU/Linux when I type

        ls SPC C-q C-v C-q C-m

In other words, `ls' is getting a single argument, of a single
character, namely carriage-return.  Why Bash isn't treating it as
whitespace is a mystery.

That makes sense.
