* bug#14357: 24.3; Directory tracking in ansi-term broken

Using ansi-term's escape-code-based directory tracking causes extra data
to be displayed in local sessions.

To reproduce this bug, run emacs using the command `emacs -Q'. Issue the
command `M-x ansi-term' run a local bash session. Issue the command `echo
-e "\033AnSiTc" $(pwd)' to simulate setting the default-directory for
the ansi-term buffer. This will be successful, but the character
sequence `^Z/cwd', where cwd is the current working directory, will also
be printed. The same happens with the escape sequences to set the user
and hostname.

A possible candidate for this bug is the variable `handled-ansi-message'
in `term.el'. It appears as though this variable is set to true at line
2740 upon processing the directory-tracking escape sequence
(`^[AnSiT...'), which prevents the following escape sequence from being
processed at line 2902, causing this second escape sequence to be
printed to the terminal instead.
