#20 Handle 'git status' output when the operation takes time

[Jose Santiago]

When 'git status' can take seconds to complete, the output of the command can look like:

  # On branch master
  # Changes not staged for commit:
  #   (use "git add <file>..." to update what will be committed)
  #   (use "git checkout -- <file>..." to discard changes in working directory)
  #
  #     modified:   .gitignore
  #
  #
  # It took 2.60 seconds to enumerate untracked files. 'status -uno'
  # may speed it up, but you have to be careful not to forget to add
  # new files yourself (see 'git help status').
  no changes added to commit (use "git add" and/or "git commit -a")

In which case 'gits statuses' and 'gits status' fails with an error similar to:

Could not parse git status output for vf <# It took 2.05 seconds to enumerate untracked files. 'status -uno'
> <# may speed it up, but you have to be careful not to forget to add
# new files yourself (see 'git help status').

The attached patch implements a work around for this issue.
