&quot; Question

&quot; The first pattern matches the last question at the end of the file (in case there is no empty line coming after).
&quot; However, it slows down parsing (and especially scrolling up), therefore it is commented out.

&quot;syn match giftQuestion  &quot;[^{[:space:]]\_.\{-}\%$&quot;                                               keepend  contains=@giftCEF,giftAnswer,giftAnswerNum
