Bug#742364: Please clarify if how sourceless file could be corrected and how

[bastien ROUCARIES <roucaries.bastien@gmail.com>]

Package: debian-policy
Version: 3.9.5.0
Severity: important
control: block -1 by 736873

According to ftp masters see #736873:
>> For implementing automatic detection fo sourceless file particularly
>> minified javascript, I need some clarification about correcting
>> sourceless file.
>>
>> They are two schools on the archive:
>> - some repack the origin tarball adding the missing source to it
>> - some add it to debian patch on subdirectory debian/missing-source
>
>Either way satisfies the requirement that we ship the source. Personally
>I prefer adding missing sources to the upstream tarball:
>
> - Upstream can do it too!
> - If source and non-source are in different locations, it's easier to
>   miss the source and (needlessly) reject the package.
> - The source isn't duplicated in every .diff.gz/.debian.tar.* (though
>   this only really matters for larger sources).
