The problem had to do with reading in a SINGLE line from a file.  That
has been solved.  I'm sorry that I didn't remember the tab characters
following the word 'technology', in that line.  I was looking at a text
version when I wrote that and in that line I don't use the tab
characters.  The first line is solely to identify what file is being read.

The significant fact was that the line ended with a line feed.  The
solution was, when using CrLfFileStream to look for a carriage return
instead of for a line feed.   (Alternatively, when using FileStream to
look for a line feed instead of issuing nextLine.)
