I think setting WholeMatches to true is better also.  I haven't tested this,
but you might find problems using the return char if lineOffset finds a
partial match which also happens to be at the end of a line.

You should also consider using "is among".  I don't think this is dependent
on WholeMatches, and I believe it always tests entire lines.
