Policy for how to do deal with long lines.

The following examples all have ClauseEndsLine=true, Indentation=4, and FoldLength=25 (so that the long SELECT clause folds but the shorter GROUP BY clause does not).

Note that ClauseEndsLine is observed in STEP and TALL modes, and in CHOP mode when a line is long.
