[Bug] t0410 breakages at 2.20.1 on NonStop platform

["Randall S. Becker" <rsbecker@nexbridge.com>]

Hi All,

We’re getting some new breakages in t0410 that I can’t explain easily or
either it is the test itself at commit 0d0ac3826a. 

[Filtered]
*** t0410-partial-clone.sh ***
not ok 5 - missing ref object, but promised, passes fsck
not ok 6 - missing object, but promised, passes fsck
not ok 7 - missing CLI object, but promised, passes fsck
not ok 12 - rev-list stops traversal at missing and promised commit
not ok 13 - missing tree objects with --missing=allow-promisor and
--exclude-promisor-objects
not ok 14 - missing non-root tree object and rev-list
not ok 15 - rev-list stops traversal at missing and promised tree
not ok 16 - rev-list stops traversal at missing and promised blob
not ok 22 - gc stops traversal when a missing but promised object is reached

The first one to fail – which probably would give me a hint on others is:

The repo/.git contains the following at the time of failure:
.git/objects
.git/objects/info
.git/objects/pack
.git/objects/pack/pack-fa10eb4e855a356f0abe9c352b62b71d481918b1.idx

.git/refs/heads/master
.git/refs/tags
.git/refs/tags/1
.git/refs/tags/2
.git/refs/tags/3
.git/refs/tags/annotated_tag

Given the contents, I'm not surprised the 'rm' failed. Any help would be
appreciated in tracking down what happened.

Thanks,
Randall
