Which is what I said - they are Isearch prompts.  They show
the effect of using different faces for different parts of a
prompt.  But not necessarily "one each for every part".

I tweaked Isearch code, yes.  Irrelevant.  Your question was
about what kind of face propertizing was being requested for
minibuffer prompts.  I showed examples of propertized prompts
(for Isearch and minibuffer).

I also showed an example using the minibuffer.  Dunno what
else you want to see.  It's about applying text properties,
in particular property `face', to any or all parts of the
minibuffer prompt, and not having that overridden by Emacs.

"So once again," it escapes me what you are having trouble
understanding about this.  Hopefully someone else can be
more helpful than I.  Lars pointed you to bug #12377, but
I guess that didn't help either.

(And yes, it is possible to remove `face' from
`minibuffer-prompt-properties', which is how I am able
to use a prompt that has parts that are propertized
with `face'.  But that means foregoing having face
`minibuffer-prompt' by default.)

The request of bug #12377 is for Emacs to use face
`minibuffer-prompt' _by default_, but not for it to override
text properties (e.g. `face') that are already in the prompt
string.  That's all.
