File System Providers vs Debug

[hoehrmann]

Issue Type: Bug

When a debug session is started from a text editor bound to a file system provider like vscode-sshfs, the debugger is initialized with DebugProtocol.InitializeRequestArguments.pathFormat set to path (and vscode-debugadapter also does not support any other pathFormat). Perhaps as a consequence, e.g. DebugProtocol.SetBreakpointsArguments then also contain only the path component of the actual address.

Since URI support is present in other APIs, say,

  let uri = vscode.Uri.parse('ssh://example.org/example/example.pl');
  vscode.workspace.openTextDocument(uri).then(
    doc => vscode.window.showTextDocument(doc)
  );

It would be nice if debugging features also had support for them, especially before users come to rely on the current broken behaviour.

The use case here is simplified remote debugging, I would like to connect a remote workspace folder using a file system provider like vscode-sshfs and then start a remote debug session without the need to configure elaborate path mappings and without the need to somehow synchronize local sources and remotely deployed code.
