Fix bug in paragraph detection (can be seen in test case of bug #5187):
If we want to look at the token after the next token, it may be needed to call tokenize_one() twice and not only once as done in good(). git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@40234 a592a061-630c-0410-9148-cb99ea01b6c8
