Test to demonstrate fifo buffer blank line inconsistency

Browse Source 
When "edit -fifo" reads data without a trailing newline, the fifo
buffer will not have a trailing blank line. But if there is a trailing
newline, we will get a trailing blank line. This is weird because the
trailing blank line exists for scrolling, it should not be determined
by the data read.

Add a test case to demonstrates the inconsistency which is fixed by
the next patch.
