[lmi] Incidental differences on first commit and push of 2019

[Greg Chicares]

I didn't expect the line about a new ECDSA host key:

/opt/lmi/src/lmi[0]$git push
Warning: Permanently added the ECDSA host key for IP address '209.51.188.201' 
to the list of known hosts.
Enter passphrase for key [REDACTED]
...
Writing objects: 100% (647/647), 188.07 KiB | 8.18 MiB/s, done.
Total 647 (delta 611), reused 162 (delta 138)
   f81b0c002..9c80545eb  master -> master

but apparently the explanation is that gnu.org's IP address changed
on 2018-12-20:
  https://savannah.gnu.org/forum/forum.php?forum_id=9330
and this was my first push since then. The new IP really does seem
to be for Hurricane Electric as the savannah announcement says:

$traceroute 209.51.188.201
... 100ge3-2.core1.bos1.he.net (184.105.64.54)  39.675 ms  41.614 ms 
kvmhost0.fsf.org (209.51.188.180)  42.182 ms

so everything seems fine.

It is probably even less noteworthy that I got this message:
  Auto packing the repository in background for optimum performance
from git when I committed a copyright update for every source file.
There, the trigger might have been the large scope of that commit,
which perhaps caused the number of loose objects to exceed 'gc.auto'.

Because it's a new year and I hadn't expected that "auto packing"
message, I thought perhaps I should run git-fsck:

/opt/lmi/src/lmi[0]$git fsck

    Install wxPdfDocument using Git instead of snapshot download

I don't know why that commit would be dangling, but apparently
it has been applied in some way, perhaps here:

/opt/lmi/src/lmi[0]$git log --grep 'Install wxPdfDocument'
commit 05a4a41aeb0273aaed7dc1bf8c872764d5ea50b7
Author: Gregory W. Chicares <address@hidden>
Date:   2015-08-07T00:25:15+00:00

    Install wxPdfDocument library as part of lmi installation

...so I suppose I should just ignore it and wait for git to
clean it up automatically someday.
