Bug or feature? 'c' in dired-mode changes buffer layout

[Marius Hofert]

Hi,

I am wondering if the following behavior is a bug or a feature:

1) open an Emacs buffer
2) Split the buffer via C-x 2
3) Change to dired mode via C-x d; now you have two buffers on top of each
other, one in dired mode
4) use 'c' in the buffer in dired mode to get a shell; instead of two buffers on
top of each other (one of which is a shell), the buffer-split is removed and the
shell is displayed as a single buffer in the frame. 

(this is on Emacs 24, Ubuntu 12.04). 

Cheers,

Marius
