Explicitly state that one tab counts for 8 columns in package
description, leaving 62 characters to the text itself.
Update the text and the example in the two places where the Config.in
format is described.
Also mention a newline is expected between the help text itself and the
upstream URL.

This blob can help developers to understand the expected formatting.
Also, it can be referenced by reviewers.
