SYNOPSIS
string set_prompt(mixed prompt, object ob)
DESCRIPTION
Set the prompt given by the first argument for the interactive
object instead of the default prompt. If the second argument
is omitted, this_player() is used as default. The first arg
can be a string or a closure.
The result returned is the old prompt.
If the first arg is the number 0, the prompt is not changed,
just returned.
