md5sum on my linux box returns a '-' in the second column if the md5sum
is being performed on standard input.  I assume that you are using an
older version on your linux system if yours doesn't do that.

Inspecting the source, I see that the '*' means that the file is binary.

As to why these changes were introduced, you'd have to ask the authors
of textutils.
