** [tickets:#168] "Broken" Pane Title when Spawning New Shell**

Brief Description
----------------------
Under tmux with powerline, when spawning a new shell (via chroot, su,
sh, etc.) the pane title is statically set to the name of the spawing
process.
**Expected Behaviour**: Pane title behaves as if spawned shell was
parent shell (i.e is set to `pwd` or currently executing program).
Environment
-----------------
Just in case it becomes relevant, I'm running on the following system:
$ uname -r
Linux bmw-mac 3.17.3-1-ARCH #1 SMP PREEMPT Fri Nov 14 23:13:48 CET 2014
x86_64 GNU/Linux
Here's my tmux version:
$ tmux -V
tmux 1.9a
My powerline is at the following commit without any local modifications:
$ cd $HOME/.powerline; git rev-parse HEAD
92e9a9d72721764bc8dc10ff53ac89b7e806ec0c
Reproduction
------------------
1. Start tmux, loading
<local_powerline_repo>/powerline/bindings/tmux/powerline.conf
1. Once tmux is running with powerline, execute `bash`
1. Notice how the current pane is now titled "bash" not as $PWD.
1. Execute `sleep 5` (or any command) and notice how the title still remains
set as "bash".
Notes
--------
* A corresponding ticket under powerline was also filed and closed as this is
"isn't a powerline issue":
https://github.com/Lokaltog/powerline/issues/1192#event-200009279
* Yes, technically, the pane title is (correctly) set to the currently running
process.
* We probably don't want to change the pane title for *every* spawn of a spawn,
only for "shell-like" processes.
* I'm willing to hack on some code with a bit of direction if necessary.
