Cover blindspots in the testing of stdin handling, including the
"!len" condition added in b5d97e6b0a0 (pack-objects: run rev-list
equivalent internally., 2006-09-04). The codepath taken with --revs
and read_object_list_from_stdin() acts differently in some of these
common cases, let's test for those.
The "--stdin --revs" test being added here stresses the combination of
--stdin-packs and the revision.c --stdin argument, some of this was
covered in a test added in 339bce27f4f (builtin/pack-objects.c: add
'--stdin-packs' option, 2021-02-22), but let's make sure that
GIT_TEST_DISALLOW_ABBREVIATED_OPTIONS=true keeps erroring out about
--stdin, and it isn't picked up by the revision.c API's handling of
that option.
