Comment 4 for bug 1773842

As long as "snap list" output remain the same and have no intention to change the output in the future, I guess it should be fine, I've been testing "sosreport" expected output with a similar command.

The intent of this bug was to have a more fancy way to do it, but again I'm fine with manipulating "snap list" with awk, tail and family, if this wishlist is not in the snap scope.
