If I copy a promt form the '*shell*' buffer with
'comint-prompt-read-only' equal 't' into the '*scratch* buffer then I
get the following with 'C-u C-x =':
,----
| character: $ (044, 36, 0x24, U+0024)
| charset: ascii (ASCII (ISO646 IRV))
| code point: 36
| syntax: w which means: word
| category: a:ASCII l:Latin
| buffer code: 0x24

| There are text properties here:
| font-lock-face [comint-highlight-prompt]
| inhibit-line-move-field-capture t
| rear-nonsticky t
| fontified t
| front-sticky (read-only)
`----
I don't know if this is correct but it seems read-only is still there.
The .emacs looks like follows:
,----[ .emacs ]
| (global-font-lock-mode t)
| (require 'comint)
|
| (setq comint-prompt-read-only t)
`----
The variable yank-excluded-properties's value is
,----
| (read-only invisible intangible field mouse-face help-echo local-map
| keymap yank-handler)
`----
