My inferior shell is bash.  I have confirmed that this problem exists
with 'emacs -Q'.  Re-setting my PS1 to the bash default PS1='\h:\w\$ '
and starting Emacs didn't help either.

Steps to reproduce:
1. emacs -Q
2. M-x ansi-term RET RET
3. cd /tmp (or any other directory)
4. C-x C-f 

Expected behavior:
Emacs will indicate the shell's working directory (/tmp) in the
find-file minibuffer prompt.

Actual behavior:
Emacs indicates the Emacs working directory working directory ($HOME,
for me) in the find-file minibuffer prompt.

I found that if I revert commit aad65192332dfc4a1df0cd2953554c21da243b51
the problem goes away.

Good.  So we can revert beaab89896 before 25.1.
We should still keep it a bit longer, in case some other project has
failed to notice the obsolescence of $EMACS.

OK, it's been ten months and that should be long enough, so I reverted it in emacs-25 (see attached patch) and am closing this bug report. Yay! One less blocker for Emacs 25! (The fixed Bash isn't out yet, alas.)
