[PATCH] vcs_info git: error before start of rebase

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

The following:

    1. git rebase -i HEAD^
    2. While editor is running, open a shell.

... results in a warning message before the prompt:

    VCS_INFO_get_data_git:208: no such file or directory: .git/rebase-merge/done                                                                             
Proposed fix:

diff --git a/Functions/VCS_Info/Backends/VCS_INFO_get_data_git b/Functions/VCS_Info/Backends/VCS_INFO_get_data_git
index 48d552f..c348da2 100644
