Output to buffer creates a new buffer

[Andrei S. <lis...@gm...>]

I was wondering if it's possible not to kill and create a new output
buffer every time.
It messes up the buffer layout on the screen.
So instead of
(if results-buffer
   (kill-buffer results-buffer))

put something like:

(when results-buffer
     (set-buffer results-buffer)
     (erase-buffer))

Same goes with the error/msg buffers.

Thank you,
Andrei
