connect.c: stop conflating ssh command names and overrides
dd33e07766 ("connect: Add the envvar GIT_SSH_VARIANT and ssh.variant
config", 2017-02-01) attempted to add support for configuration and
environment variable to override the different handling of
port_option and needs_batch settings suitable for variants of the
ssh implementation that was autodetected by looking at the ssh
command name. Because it piggybacked on the code that turns command
name to specific override (e.g. "plink.exe" and "plink" means
port_option needs to be set to 'P' instead of the default 'p'), yet
it defined a separate namespace for these overrides (e.g. "putty"
can be usable to signal that port_option needs to be 'P'), however,
it made the auto-detection based on the command name less robust
(e.g. the code now accepts "putty" as a SSH command name and applies
the same override).
Separate the code that interprets the override that was read from
the configuration & environment from the original code that handles
the command names, as they are in separate namespaces, to fix this
confusion.
This incidentally also makes it easier for future enhancement of the
override syntax (e.g. "port_option=p,needs_batch=1" may want to be
accepted as a more explicit syntax) without affecting the code for
auto-detection based on the command name.
While at it, update the return type of the handle_ssh_variant()
helper function to void; the caller does not use it, and the
function does not return any meaningful value.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from http://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git, http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
