## description:
#   action:   a string that signals a certain non-default condition in the
#             repository (like 'rebase-i' in git). If this in non-empty,
#             the actionformats will be used, too.
#   branch:   the name of the currently checked out branch.
#   base:     the full name of the repository's root directory.
#   staged:   non-empty if the repository contains staged changes.
#   unstaged: non-empty if the repository contains unstaged changes.
#   rev:      an identifier of the currently checked out revision.
#   misc:     a string that may contain anything the author likes.
#             the backends should document what they put in it and when.
#
# If an argument has no valid value for a given backend, an empty value
# should be provided. eg:
#   VCS_INFO_formats '' "${foobranch}" "${foobase}" '' '' '' "${foomisc}"
