Git SSH operations do not work after git update to version 2.16.0 if ssh URL contains a port

What steps will reproduce the problem?

1. Add a remote with SSH and a port
2. Context menu on repository directory -> Tortoise Git -> Pull | Fetch | Push | ...

What is the expected output? What do you see instead?

Expected:

The pull|fetch|push|... operation runs successfully.

Actual:

git.exe fetch -v --progress "origin"

fatal: ssh variant 'simple' does not support setting port


git did not exit cleanly (exit code 128) (62 ms @ 19.01.2018 17:32:15)

What version of TortoiseGit and Git are you using? On what operating system?

• OS: Win 7
• Git: 2.16.0.windows.2
• TortoiseGit: 2.5.0.0
• OpenSSH: 7.6p1
• OpenSSL: 1.0.2n

Please provide any additional information below.

pull|fetch|push|... work correctly if invoked via command line in the CMD though.
