Problem with includesfile in jar task.

[Chris Stillwell]

I noticed that if a filename within the file specified by the includesfile
attribute contains any trailing blanks, then the file is not included in the
jar and no errors are indicated.  I can easily fix my file, but I would
think that whichever method is reading in these file patterns would do a
trim to truncate trailing blanks.

I would also like to know if it is possible to have the jar task fail if a
file is not found and can't be loaded.  The whenempty attribute should fail
when the entire jar is empty, but what about when the jar is missing some
required piece(s).
