[PATCH v5 0/2] commit-graph: use start_delayed_progress()

Thanks, Ryenus, for reporting this problem.

Update in V3:

Based on our discussion, I've added the suggested GIT_PROGRESS_DELAY environment variable. This allowed the existing tests to stick around with one exception in the GC tests. The test remains, but we can no longer look at the commit-graph output.

Update in V4:

The GIT_PROGRESS_DELAY check is extracted to a helper method so it can be used with start_delayed_sparse_progress().

Update in V5:

I took Peff's advice for using "env" to use this delay in the GC test.

  progress: create GIT_PROGRESS_DELAY
  commit-graph: use start_delayed_progress()

          The tests that check for the progress output have already been updated
     -    to use GIT_PROGRESS_DELAY=0 to force the expected output. However, there
     -    is one test in t6500-gc.sh that uses the test_terminal method. This
     -    mechanism does not preserve the GIT_PROGRESS_DELAY environment variable,
     -    so we need to modify check on the output. We still watch for the
     -    "Enumerating objects" progress but no longer look for "Computing
     -    commit graph generation numbers".
