doc says MunkiImporter output var pkg_repo_path will be empty for existing matching item but it's populated

[codeskipper]

Describe the problem
Documentation says MunkiImporter Output variable pkg_repo_path will be empty if item is not imported, but I find it is populated if a matching item has already been imported (in an earlier session).

Documentation
%autopkg processor-info MunkiImporter

...
pkg_repo_path:
   description: The repo path where the pkg was written. Empty if item not imported.

It looks to me like the output variable is for this code path is set here

AutoPkg output
% autopkg run -vv Firefox.munki.recipe

Expected behavior
Either the documentation for the processor should be updated to state what to expect for output variable pkg_repo_path in the case of an existing item that matches, or the code should be corrected to do what the doc says so pkg_repo_path is returned empty in this case.

Maybe the docs could say something like this:

pkg_repo_path:
   description: The repo path where the imported installer was written, or where a matching installer was found. Empty if item not imported or found in the repo at all.

Even better (more consistent) would be if pkginfo_repo_path would also be populated in the case of an existing matching item in the repo, but I'm guessing that would take significantly more of an effort.
