Proper suffix to repack a tarball with doxygen generated docs

[Joan Lledó <jlledom@mailfence.com>]

Hello,

I'm the maintainer of the lwip package. The orig tarball includes some
doxygen generated files, that trigger the lintian "source-is-missing"
error[1].

I'm going to repack the tarball to remove those files, but I'm not sure
about which suffix should I use.

Should I use "dfsg", b/c the orig includes some minified JS that are not
readable nor modifiable? Is "ds" more appropriate for this case? or any
other?

Thanks!
