git-2.12.3-1: Cannot push to a remote with a Windows network path URL

[Jonathan Chan <jdc dot d3v at gmail dot com>]

After updating to git-2.12.3-1, I have been unable to push to a remote
with a Windows network path URL:
    $ git push origin
    Counting objects: 3, done.
    Delta compression using up to 4 threads.
    Compressing objects: 100% (2/2), done.
    Writing objects: 100% (3/3), 273 bytes | 0 bytes/s, done.
    Total 3 (delta 1), reused 1 (delta 0)
    remote: error: object directory
/network/path/to/git-repository/objects does not exist; check
.git/objects/info/alternates.
    remote: fatal: unresolved deltas left after unpacking
    error: remote unpack failed: unpack-objects abnormal exit
    To file:////network/path/to/git-repository
      ! [remote rejected]   master -> master (unpacker error)
    error: failed to push some refs to 'file:////network/path/to/git-repository'

Notes:
- Fetching works
- Pushing works if I use EGit (in Eclipse)
- Pushing works if I change the remote URL to use a drive mapped to
the network path

Additional searching turned up Issue #979 on git-for-windows:
    https://github.com/git-for-windows/git/issues/979

Issue #979 appears to have been fixed in git and included in
2.11.1..2.13.1 releases:
    https://github.com/git/git/commit/7814fbe3f1e7cea1a675408df7b5dd1f5be731cc

I did not encounter this behavior prior to git-2.12.2-1. This is for x86_64.
