Git branch slow on windows - nvim about aw-watcher-vim

[infokiller]

Thanks @ErikBjare for the quick fix!

I think this is important, syncronous commands can be quite slow. aw-watcher-vim already did shell commands prior to this change, but they did so asyncronously, so it did not have an impact on responsiveness. There is nothing more annoying than an unresponsive editor!

I think that the branch detection should be made asyncronous as well. It's also a bit excessive to check git branch on pretty much every time you move the cursor.

I can confirm this makes editing in vim totally unusable.
@johan-bjareholt @FilipHarald I think this change should be reverted until there's a more efficient async implementation working.

Totally agree with you @johan-bjareholt. It would be sufficient to get the branch on buffer change for instance and save it as a global variable instead.

[johan-bjareholt]

Maybe just checking every 10-60seconds (possibly configurable) and do it asynchronously would probably be good. Should be a bit more reliable than a buffer change.

Ah, my bad. I can look into it this weekend. But I can't promise I'll solve it :)

[ErikBjare]

@infokiller I agree, it was my bad to merge too eagerly. Reverted now, see #25 (comment)
