Yes, it's actually a feature, not a bug. :-)
Use `M-n' if you need to see the default value.
If you really want to see the default value in the prompt, then do surgery on
the definitions of `describe-function' and `describe-variable', to replace the
prompts in their calls to `completing-read'. Just compare the `completing-read'
calls in `help-fns.el' (vanilla) and `help-fns+.el':
vanilla (what you like):
(if fn
(format "Describe function (default %s): " fn)
"Describe function: ")
+ (what I like):
(if current-prefix-arg
"Describe command: "
"Describe function: ")
You would replace each of those prompt strings by a conditional such as the one
in help-fns.el.

[FWIW, I use Icicles, which lets the _user_ decide whether to put the default
value in the prompt. That's one reason I do not hard-code it into prompts.
Option `icicle-default-value':
nil - Do not insert default value or add it to prompt.
t - Add default value to prompt. Do not insert it.
`insert-start' - Insert default value and leave cursor at start.
`insert-end' - Insert default value and leave cursor at end.
`preselect-start' - Insert and preselect default value;
leave cursor at beginning.
`preselect-end' - Insert and preselect default value;
leave cursor at end.
The default value is `t', which gives the behavior you like. Personally, I use
the value `insert-end'.]
