RE: [ANNOUNCE] Git v2.22.0-rc2

Just a few small nits from RC2 test results on the NonStop TNS/E platform:

1. t0021 subtest 15 is being flakey. It fails on the first run (make -k test) but succeeds when run in isolation. This is new on the NonStop TNS/E platform. t0021 has been a bit flakey in the past, but not recently. Just thought I'd mention it. It's only slightly disconcerting because I make very heavy use of smudge filters but since it runs fine in isolation, I'm going to assume it is fine. We had one unsubstantiated report of an occasional misfire of smudge filters, but no substantive evidence at this point to reproduce the situation.

2. t7519 subtest 25 still does not pass (previously reported for RC1) when run via "make -k test" the first time. This runs successfully when run in isolation or the second time.

3. t9001, t9020, t9600, t9601, t9602, t9604, fail, but should not run on platform (not new, just a reminder). We do not have sendmail or subversion.

So it looks like we're a go on RC2 on NonStop.

Thanks, Randall
