MFS9->8 r249822:
Update error messages when processing the INDEX file to display the given
path rather than a static string. This makes the error messages consistent
with the rest of the functions which already do the same thing (assumed to
be an oversight of r47055, 13+ years ago). A direct commit to stable/9.

This is a direct commit to stable/8.
