[3/7] riched32: Test EM_LINELENGTH between carriage return & line feed.

[Dylan Smith]

Previously this wasn't properly tested for, since all the lines had text
of the same length, so it wasn't properly testing to see which line
length it was getting.  This patch modifies the test to catch the
addition inconsistency, and makes the comments clearer in what is being
tested.
