# Extend the path in `base_path` with the path in `current_segment`, returning
# the result in `joined_path`. If `current_segment` is an absolute path then
# just return it, in effect overriding `base_path`, and issue a warning.
#
# Note that the code returns a relative path (avoiding introducing leading
# slashes) if `base_path` is empty.
