Vscode-remote-release: "The command line is too long" trying to connect to a Windows SSH server

[JustinGrote]

3481 is still active on nightly 2020.10.29700, creating this new issue since that one is locked, even though the command length says 8168 characters CMD on the other side (server 2012R2 w/ openssh) says it is too long

In local testing, I removed the echos from the extension in the minified extension.js locally (since you guys don't provide an open source release), and it started working.

[roblourens]

Thanks for the suggestions. Maybe it's the extension install string that puts you over the limit

[roblourens]

Working on this, I forgot to mention that you can work around it by setting "remote.SSH.useLocalServer": true (in your settings.json). This may cause other issues though, which is why it's disabled by default on Windows.

[roblourens]

More aggressive minification, got it about 15% shorter

[JustinGrote]

@roblourens One other minification I spotted was that
if ($exts -ne "") {

The line after should reference $exts, and not be another template fill. If specifying several extensions this will cut it down a lot. Probably should be guidance to limit # of extensions requested to install since it can very quickly break the ceiling on this script length.

[roblourens]

Oops, good catch!
