I think this sounds like a good idea; consistency is good.

How about taking it even further?   Something along the lines of:

    (format-prompt PROMPT &optional DEFAULT)

    (format-prompt "Set bookmark" default)
    => "Set bookmark [foobar]: "

    (format-prompt "Goto char")
    => "Goto char: "

(This would avoid having to always remember to use double formats like
above.)
