# 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.
