tortoiseplink ssh variant still needed?

[Sven Strickroth <email@cs-ware.de>]

Hi,

Git differentiates between different variants of SSH tools.

One variant is the tortoiseplink variant. When this is configured Git 
passes passes a special "--batch" parameter and passes the port using 
"-P" (capitalized P) t the SSH tool.

IIRC tortoiseplink was initially created by TortoiseCVS which is 
nowadays not maintained any more 
(<http://www.tortoisecvs.org/download.shtml>).
In TortoiseSVN and TortoiseGit tortoiseplink was modified six years ago 
(around 2015-03-07) to ignore the "--batch" parameter and also accept 
"-p" additionally to "-P"  (cf. 
<https://osdn.net/projects/tortoisesvn/scm/svn/commits/26348>).

Therefore, my first question: Does Git still want to support very old 
versions of tortoiseplink or should I provide a patch which drops 
support for it?

Second question:
TortoiseGit comes with an even more improved version of TortoisePLink 
(named TortoiseGitPLink, but also ships the same binary as 
tortoiseplink) that also accepts "-o SetEnv=..." parameters in order to 
support the Git protocol version 2. At the moment TortoiseGit 
automatically sets the environment variable "GIT_SSH_VARIANT=ssh". This 
works, but is not perfect if other parameter of OpenSSH are used. Would 
it make sense to add a new ssh variant tortoisegitplink? If yes, how to 
handle new versions that might also support even more OpenSSH command 
line parameters?
