bug#17956: 24.3.92; Calling highlight-regexp non-interactively causes errors from face-name |

The logic within #'highlight-regexp for selecting a face is based on
previous calls. This is a good feature, however it may be the cause of
an issue where deleting the frame, visiting the same buffer in another
frame, and then calling the highlight-regexp function interactively.
This does not happen on 24.3.1.
To reproduce:
1. Start emacs:
$ emacs -Q
2. Create new frame:
C-x 5 2 <RET>
3. create buffer:
C-x b "bug" <RET>
4. (optional) Insert text:
123
5. Highlight text non-interactively:
M-: (highlight-regexp "1" "hi-green")
6. Kill frame
C-x 5 0 <RET>
7. Visit buffer on initial frame
C-x b "bug" <RET>
8. Highlight-regexp non-interactively, supplying a default argument
M-x highlight-regexp <RET> 2 <RET>
The following error is encountered:
face-name: Wrong type argument: symbolp, "hi-green"
NB: This bug does not occur when the second call to highlight-regexp is
interactive.
An alternative recipe to reproduce the bug is the following:
A. start emacs with the following script:
$ emacs -Q -l bug-highlight-regexp.el
Where bug-highlight-regexp.el contains the following:
(defun bug-highlight-regexp-non-interactive-then-interactive ()
"
Calling #'highlight-regexp non-interactively and
supplying a non-nil face parameter causes errors
with interactive calls (to #'highlight-regexp).
"
(interactive)
(let ((bug-frame (make-frame))
(bug-buffer (get-buffer-create "Bug Demo")))
(select-frame bug-frame)
(switch-to-buffer bug-buffer)
;; The regexp does not have to match, and
;; any valid face parameter can be supplied.
(highlight-regexp "anything" "hi-green")
(delete-frame bug-frame)
(with-selected-frame (make-frame)
(switch-to-buffer bug-buffer)
(message "Do `M-x highlight-regexp' with any pattern to invoke
bug\n"))))
B. Do M-x bug-highlight-regexp-non-interactive-then-interactive <RET>
C. Call M-x highlight-regexp

Mat
