Avoid an infinite loop in fts3/4 incremental-merge in the case where the lowest level in the database contains segments but no data (because there is a delete-marker for each valid entry). Fix for [bf1aab89].

Update fts3/4 so that the 'merge=X,Y' command merges at least, instead of exactly, Y segments from a single level. This matches the documentation. 'merge=X,0' is, as it was in 3.11, an error.
