#26 Concat task support for adding trailing newlines

[Dan Jagnow]

I have a set of SQL scripts that I would like to append
using the concat task. However, some of the files don't
contain a carriage return line feed at the end of the final
line. The concat task appends the files such that the
final line of one file and the initial line of the next file are
merged into a single line. It would be nice to have an
attribute on the concat task that would force the
insertion of a \r\n to avoid this problem.
