Re: emacs shell mode prompt with escape sequences "\[\033]0;\w\007"

The stock /etc/profile already does that.  However, /etc/profile is only
invoked for login shells.  A regular shell invocation inherits PS1 from
the current shell.  Contrast

igor@pechtcha ~
$ /bin/sh
\[\033]0;\w\007
\033[32m\]\u@\h \[\033[33m\w\033[0m\]
$ exit

igor@pechtcha ~
$ (exec -l /bin/sh)
alias: not found
$ exit

Note: the "alias: not found" message results from /etc/profile.d/mc.sh (as
I've reported a while ago), but it may be an ash problem.  According to
<http://www.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html>,
a POSIX-compliant shell should support the "alias" and "unalias" commands.
