Shawn Rutledge 524ab7b535 Avoid crashing when the end of an empty markdown list is detected ... The markdown parser generates empty lists in some cases when a character that can be used as a bullet is found on a line by itself. cbEnterBlock() and cbLeaveBlock() are called symmetrically in such cases. QStack::pop() on an empty stack triggers an assert, so push and pop need to be done symmetrically too. But it's difficult to actually create the list as soon as the MD_BLOCK_UL or MD_BLOCK_OL callback occurs, without breaking the case fixed in 7224d0e427 (and probably other cases). That's because QTextCursor::insertList() creates a list item at the same time as it creates the list itself, and also inherits block formatting from the previous block. We now insert empty lists with empty items whenever the need for that is detected though, and there's a failsafe to prevent popping in case something still goes wrong with that logic. We aren't strict about reproducing the original markdown when regenerating it via toMarkdown(), but it's getting closer.
