# "git rev-list<ENTER>" is likely to be a bug in the calling script and may
# deserve an error message, but do cases where set of refs programmatically
# given using globbing and/or --stdin need to fail with the same error, or
# are we better off reporting a success with no output?  The following few
# tests document the current behaviour to remind us that we might want to
# think about this issue.
