     # git-status' porcelain v1 format starts with 2 letters on each line:
     #   The first letter (X) denotes the index state.
     #   The second letter (Y) denotes the working directory state.
     #
     # The following table presents the possible combinations:
     # * The underscore character denotes whitespace.
     # * The cell values stand for the following file states:
     #   a: added
     #   d: deleted
     #   m: modified
     #   r: renamed
     #   u: unmerged
     #   t: untracked
     # * Cells with more than one letter signify that both states
     #   are simultaneously the case. This is possible since the git index
     #   and working directory operate independently of each other.
     # * Cells which are empty are unhandled by this code.
     # * T (= type change) is undocumented.
     #   See Git v1.7.8.2 release notes for more information.
