QToggle won't close QF if more than one quickfix exists

[mellery451]

I'm starting to use tabs (yes, whether tabs are useful or not is debatable....). In any event, I if I have more than one QF open, e.g. one on each tab, the QToggle does not seem to be able to close any of them. Calling :cclose directly does seem to work, so I'm, perplexed. along this same line, I'd actually like :QToggle to close all QF windows in all tabs, but that might be controversial, so I'd just be happy if it just succesfully closed the QF for the current tab.
