[sup-devel] [PATCH] ruby 1.9: use String#ord in ask_getch and ask_yes_or_no

In Ruby 1.9, character literals and the return value from string index
accesses are now themselves strings and need to be converted to integers with
String#ord. This was breaking ask_getch. Integer#ord is defined on Ruby 1.8 so
this won't cause problems there.
