So, should I package it (without replacing shells)?

Well, have a look at this snippet:

+                  (for-each (cut wrap-program <> var)
+                            files)))

Each 'file' here will have an absolute filename.

I failed to make it work with the previous version.

Should I change the commit message?

Why should I add them?

Could you elaborate?  Why is it needed?  Is it necessary to add
'python-search-paths'?
