API: Allow to use the file watcher for aribitrary folders

vscode 0.10.8, windows 10.

like in the video, branch status updated only when clicking git panel.
if auto tracking is not possible, how about update status when clicking the sync button in the status bar?

Hello. This is not a bug. It is not updating for you because you did not enter your Git credentials. After entering your git credentials, the branch automatically changes.

Hi @MystK, all operations are local. The credential error in the video is not my point, just a side effect of showing that, after pressing the sync button, the local git status is still not updated. Before that, I pressed the "master" button, this interaction also did not update the status. Until at last, I opened the git panel, new branch finally shows.
So, I expect that, clicking the "master" button or the sync button will refresh status first and show the new created/deleted branch.

Thanks for the clarification. My apologies. I've tried to reproduce your issue but cannot. I've clones your environment and steps but my branch still switches to the testing branch without having to click the Git panel.

@MystK, I just find that this happens only when using vscode open a subfolder of a git repository. working on the repository root folder works normal.

This is due to a lack of file system events within the .git folder, when scoping VS Code to a sub directory of the repository.

@bpasero Let's talk about this when you're back.

It works for me, it just takes a while...

Actually...it used to track, but it doesn't anymore. That's what I'm seeing on Windows7 anyway with the latest update.

@joaomoreno thats a tough one, would you want explicit API to listen to a .git folder in the parent chain? I think if git does not find a .git folder to listen on, it should fallback to some polling mechanism instead.
