file-name-shadow-mode and minibuffer-avoid-prompt

[Klaus Zeitler]

Symptoms:

When I set minibuffer-prompt-properties to minibuffer-avoid-prompt
and use file-name-shadow-mode, I can't get to the first char of the shadowed
part in the minibuffer. Here's an example:

1. start emacs -q --no-site-file
2. M-x file-name-shadow-mode
3. in scratch buffer evaluate:
(setq minibuffer-prompt-properties
      (append minibuffer-prompt-properties
              (list 'point-entered 'minibuffer-avoid-prompt)))
4. e.g. C-x C-f 
   scratch buffer looks e.g. like: "Find file: ~/"
5. enter e.g. a 2nd "/"

I can't move the cursor to the "~".
I also noticed, that when cursor is in the shadowed part, C-a wont move the
cursor to the first char, instead it moves the cursor out of the shadowed part.
