Corrected the lyric preview logic in regards to the pitch shift grouping behavior.  A pitch shift automatically groups with the previous syllable (non pitch shift lyric), but doesn't affect the grouping of the next syllable.  For example, "a-" "+" "b" should group as "a-+b" and "a" "+" "b" should group as "a+ b".
