Add the possibility to change the [...] pattern in "Fill blanks" question type
I've got e test and a "Fill blanks" question.
I cannot put texts with square brackets in my text, because if I do so, it became a txte to find.
Most advanced teachers add
[ and ] to replace bracket for display, but they have to re-replace it each time the edit the question.
May be we could add an option that allow user to other characters than [ and ] to define word to find in Fill blanks questions.
