WHENCE: Add "Info:" tag to text that's clearly not part of the license

In general text that comes after "License:" but before any other tags
(or section separators) should be assumed to be part of the
license. However, in some cases random information is placed there
that really doesn't have anything to do with the license. Add an
"Info:" tag before this extra bit of information to make it easy for
tools to find the license from the WHENCE.
