  15  *
  16  * <grist> is salt to distinguish between targets that otherwise would
  17  * have the same name:  it never appears in the bound name of a target.
  18  * (member) is an archive member name: the syntax is arbitrary, but must
  19  * agree in path_parse(), path_build() and the Jambase.
  20  *
  21  * On VMS, we keep track of whether the original path was a directory
  22  * (without a file), so that $(VAR:D) can climb to the parent.
