In some situations new files are not shown in the unstaged files with pending active.

I'm not sure what these situations are yet.

The git command used by sourcetree is: 

`git -c diff.mnemonicprefix=false -c core.quotepath=false --no-optional-locks status --porcelain --ignore-submodules=dirty --untracked-files=all --no-ahead-behind` 

Which includes them prefixed with `A`, however sourcetree refuses to show them in Pending or Untracked, only in Clean and All.

This is an annoying bug since you may forget to add files.
