~/.emacs_bash setting PS1

[Samuel Karl Peterson]

I set my PS1 prompt so that it highlights the hostname portion of my
PS1 string.  I use different colors on different hosts so I have a
better visual cue as to which host I'm actually logged into (had some
mishaps in the past with running the wrong command on the wrong
machine).  It looks like this:

export PS1="[\u@\[\033[1;35m\]\h\[\033[0m\] \W]$ "

Unfortunately, in Emacs shell-mode, this doesn't show up correctly.  I
don't need for it to work in shell-mode.  The info manual says that
shell-mode reads the file ~/.emacs_SHELL depending on the shell used
(I use bash).  However, placing the above line into the ~/.emacs_bash
file doesn't seem to work.  Oddly enough, I can type 'exit' and then
I'll have a shell with the proper PS1 variable set.

Anyone have any advice for me?
