emacs: run-octave captures the shell directory tracker

[Francesco Potorti`]

Package: emacs
Version: 22.1+1-2
Severity: minor

I will try to work on this, but due to lack of time I am not sure I will
be able to.  Workaround is:

M-x shell RET
octave RET
M-x rename-buffer RET octave RET
M-x load-library RET octave-inf RET
M-x inferior-octave-mode RET

In GNU Emacs 22.1.1 (x86_64-pc-linux-gnu, GTK+ Version 2.10.13)

emacs -nw -Q
M-x run-octave RET (you need to have octave installed)
C-x o
M-x cd RET /var RET
M-x shell RET
M-x set-variable RET debug-on-error RET t RET
cd log RET         (this is done inside the shell buffer)

Debugger entered--Lisp error: (error "No such directory found via CDPATH 
environment variable")
  signal(error ("No such directory found via CDPATH environment variable"))
  error("No such directory found via CDPATH environment variable")
  cd(#("log" 0 3 (fontified t)))
  inferior-octave-directory-tracker(#("cd log\n" 0 6 (fontified t) 6 7 nil))
  run-hook-with-args(inferior-octave-directory-tracker #("cd log\n" 0 6 
(fontified t) 6 7 nil))
  comint-send-input()
