Now that we changed this method, very fast commands show no progess at
all. This means we need to stop testing for seeing these progress lines
in the test suite.

I think this is OK for now, though it does make me wonder if
"--progress" ought to perhaps override "delayed" in some instances,
since it's a positive signal from the caller that they're interested in
seeing progress.

I was thinking that we could start with a GIT_TEST_PROGRESS environment
variable to force all delayed progress to act like non-delayed progress.
That would at least give us confirmation on these kinds of tests.

I think this could actually be a non-test variable. E.g., something like
this:

diff --git a/progress.c b/progress.c
index 0063559aab..74b90e8898 100644
