R devel - Apr 2006 - bash-like history mechanism and prompt settings

Hi,

I have a couple of questions:
* would it be possible to add more information on the history, for 
example the number of the command and a timestamp. With the number of 
command, one could do some stuff like in a terminal to recall a specific 
command :
$ !45
and with the timestamp, one could imagine to ask for commands that were 
typed in a given interval of time. For example :
R> history(before="Thu Apr 13 8:54:14 2006")

* My other question is about the prompt, is it possible to make it 
dynamic, ie to mimic the PS1 variable in bash. R would use a prompt that 
would tell (for example) the current time, and the number of the command 
to come
[445-10:58:54] R>

(I'm using R from gnome-terminal on fedora 5)

Regards,

Romain
