LGTM, thank you.  Pushed to `master`.

Assuming one has an Emacs repo at ~/src/emacs/trunk,

1. emacs -Q
2. C-x C-f C-a C-k ~/src/emacs/trunk/*/minibuf TAB
3. The minibuffer contents change to
   ~/src/emacs/trunk//minibuf
4. Since there's a //, subsequent file name completion tries to complete
   on the root directory, which is not what should happen.

A more concise reproduction:

(completion-pcm-try-completion
 "*/minibuf" '("lisp/minibufA" "src/minibufB") nil (length "*/minibuf"))

evalutes to

("/minibuf" . 8)

We should be preserving the *.  A patch to fix this will follow.
