Fortunately [1] says

  Not all copyright notices may apply to every individual file

so a pointer to there might be enough to remove the ambiguity for the
Copyright field.

[2] says

  This field should include all text needed in order to fulfill both
  Debian Policy's requirement for including a copy of the software's
  distribution license (12.5), and any license requirements to include
  warranty disclaimers or other notices with the binary package.

but doesn't speak to what to do when e.g. license requirements or
warranty disclaimers vary between files matching the file pattern.

Thanks,
Jonathan
