Bug#736360: lintian: do not warn about doxygen embedding jquery

[Helmut Grohne <helmut@subdivi.de>]

Package: lintian
Version: 2.5.2
Severity: normal

Dear Maintainers,

Please stop warning about jquery.js as embedded by Doxygen. I evaluated
all options at fixing this issue in Doxygen and conclude that a fix is
infeasible and its usefulness is limited. The issue and the problems
about fixing it are documented in /usr/share/doc/doxygen/README.jquery
(in the doxygen package >= jessie). Even if there were a security issue
in jquery, it will likely not affect any user via Doxygen.

For detection I suggest to look for doxygen.png and doxygen.css. If both
are present, the jquery warning should be suppressed.

Note that some maintainers have started replacing jquery.js in response
to the lintian tag. Unfortunately what is named jquery.js does not only
contain jquery. Thus some generated documentation is now broken. I would
like lintian to error out if jquery.js of Doxygen-generated
documentation is a symbolic link to the jquery package. Do you need a
separate bug number for this?

Thanks

Helmut
