i think the problem is that when parsing quot(), empty lines 
are not flushed via sendOnEmptyLinesEvent before fContext.beginQuot 
is called. 
they are flushed later when parsing line() (i.e. quot->quotLine->line)
which confuses the InternalWikiScannerContext.

i attached a patch which solves the problem for me, but also changes the
way quote-lines are "grouped" to quotes.
