In american english sentences like the following ones are
quite common:

1) "blah blah blah". Some more blah...
2) "blah blah blah." Some more blah...
3) "blah blah blah.  Some more blah...

Now, the 3rd gives out the problem. For example, here it is an excerpt fooling
my parser:

Party chairwoman Hazel Blears was accused by the Conservatives of scapegoating immigrants after saying in an Independent on Sunday newspaper interview: "We have got areas in Salford where private landlords are letting properties with 10 and 12 people in there. "Now, the community doesn't object to the people - they object to the exploitation and the fact that that leads to people being on the street drinking, anti-social behaviour." Welsh Secretary Peter Hain, meanwhile accused Home Secretary John Reid of "fanning up" last week's row over
stop-and-question powers possibly being rolled out across the UK.

One way around is feeding a UTF-8 .ly file to Flex, and require that the proper Unicode “...” be used, i.e. U+201C & U+201D. When U+201C arrives, in the lexer, start parsing a quotation string. If the closing U+201D has not arrived when the paragraph, or whatever block without the construct cannot survive, closes, issue an error.
