It also might be handy to be able to reset the info once it is determine
that a file is, in fact, identical.  This would be the case if someone
edits a file, and then undoes the changes, and writes the result out.
Or a common scenario I do:

  - Delete all of the source files.
  - Extract a tar file of the next version of the distribution.
  - tree-lint, inventory, and what-changed to find out what happened.

Many of these files will remain the same, even though their inodes are
now different.
