Oops, that would be non-trivial substitution. It's more like

  PATH_MAN_ADD bin ../man
  PATH_MAN_ADD .bin ../.man
  PATH_MAN_ADD /usr/bin ../share/man

And the code for third example would look smth like

  # set by PATH_MAN_ADD first and second argument
  from=/usr/bin
  to=../share/man

  case "$path" in
    *$from) p="$path/$to"
            p=$(realpath $p)
            add_to_manpath "$p"
            ;;
  esac
