Using the YesOrNo() function consecutively, garbage input results in the
"Please answer yes or no.>" prompt being repeated until a valid "yes" or "no" is entered. However, if one types "no" at the first prompt, then just presses
Enter at the second prompt, the game treats this as if "no" was entered
and moves on to the next question. To get YesOrNo() to repeat the question, add a condition around the 3
existing lines in verblibm.h The condition should be (parse->1) for Z-code, and (parse-->0) for glulx.
