While you may not have been explicit enough, I was not smart enough.
That escape-hatch exists *already*. And it is exactly the thing that you
mentioned earlier as a potential source of mis-identification.
Let's assume that you want to use a script for the GIT_SSH_COMMAND that
eventually uses PuTTY, and you call this script "junio-is-a-superstar.sh".
All plausible so far ;-)
Now, with the patch in question (without the follow-up, which I would like
to ask you to ignore, just like you did so far), Git would not figure out
that your script calls PuTTY eventually. The work-around? Easy:
DUMMY=/plink.exe /path/to/junio-is-a-superstar.sh
In other words: the thing that we thought may be a problem is actually a
feature.
Likewise, if your GIT_SSH_COMMAND looks like this:
THIS_IS_NOT_ACTUALLY_PUTTY=/my/window/needs/putty my-ssh.sh
... you can easily change Git's mind by prefixing
DUMMY=blubber
If you want to use a script that decides itself whether to call OpenSSH or
PuTTY, Git should "stay dumb" about it, as it will not be able to tell
beforehand whether a port argument should be passed via `-p` or `-P`
anyway.
Of course, given our discussion I think all of this should be documented
in the commit message as well as in the man page.
Do you agree this is a good direction to take?
Ciao,
Johannes
