/* Note that this test used to fail worse than it does now. The
   current situation isn't hugely critical, though probably still
   incorrect.

   There are two key portions of the string: the "ing" (which gets
   contracted to one character) and the double space at the end. When
   translated, you get: "greetings " -> "greet+s " Notice that the
   translation also contracts the double space into a single space.

   With regard to cursor position, compbrlAtCursor is set, which means
   that the word encompassed by the cursor will be uncontracted
   (computer braille). This means that if the cursor is anywhere
   within "greetings", the translated output will also be "greetings",
   so the cursor positions are identical up to the end of the s
   (position 8).

   It gets more interesting at position 9 (the first space). Now,
   greetings gets contracted, so the output cursor position becomes 7.
   Still correct so far.

   Position 10 (the second space) is the problem. Because
   compbrlAtCursor is set, the current word should probably be
   expanded. In this case, it is just a space. However, the two spaces
   are still compressed into one, even though the second should have
   been expanded. The translation has still contracted the second
   space, even though it should have stopped contracting at the
   cursor.
