# Helper function for VCS_INFO_detect_*
#
# Usage:
# vcs_comm[detect_need_file]=FILENAMES VCS_INFO_bydir_detect DIRNAME
# where DIRNAME is a directory name and FILENAMES is a space-separated list
# of filenames.
#
# If any parent directory of the current working directory, other than the root
# directory, contains a subdirectory named DIRNAME that contains a file whose name
# is in FILENAMES, set vcs_comm[basedir] to the path of that parent directory and
# return true. Otherwise, return false.
