fixed bug about localized guide-key/highlight-command-regexp

[aki2o]

The command that is matched by guide-key/highlight-command-regexp was not highlighted even if
the following config was set.

(defun guide-key/my-hook-function-for-org-mode ()
  (guide-key/add-local-guide-key-sequence "C-c")
  (guide-key/add-local-guide-key-sequence "C-c C-x")
  (guide-key/add-local-highlight-command-regexp "org-"))
(add-hook 'org-mode-hook 'guide-key/my-hook-function-for-org-mode)

Then, I found the cause.
guide-key/highlight-command-regexp is a buffer local variable but is read in the guide-key/guide-buffer-name buffer when execute guide-key/popup-function.

So, I've made guide-key/popup-function pass guide-key/highlight-command-regexp to guide-key/get-highlight-face.

Is this trouble a degraded bug?

Thanks a lot.
I made this bug in 2c2d031 by mistake.
