Title: Debug for c46f027

PROMPT_COMMAND
If set, the value is executed as a command prior to issuing each
primary prompt.

PROMPT_COMMAND cannot contain a script but only ONE command (at least on
bash 3.2.48 from Mac OS X Lion)

The solution is to call the old prompt command at the start of
__set_bash_prompt()
