I do not mind phrasing "original FD #1" as "original standard
output" at all.  I just wanted to make sure it is clear to readers
whose FD #1 and FD #5 we are talking about. In other words, the
readers should get a clear understanding of where they are writing
to, when the code they write in test_expect_success block outputs to
FD #1, and what the code needs to do if it wants to always show
something to the original standard output stream.
