Bug#553493: lintian: usr-share-doc-symlink-without-dependency doesn't find indirect dependency

[Ove Kaaven <ovek@arcticnet.no>]

Package: lintian
Version: 2.2.17
Severity: normal

I have

E: wine-bin-unstable: usr-share-doc-symlink-without-dependency libwine-unstable
E: wine-unstable: usr-share-doc-symlink-without-dependency libwine-unstable

But wine-unstable has a versioned dependency on wine-bin-unstable,
and wine-bin-unstable has a versioned dependency on libwine-bin-unstable,
and libwine-bin-unstable has a versioned dependency on libwine-unstable.
(All of these dependencies are, of course, strict "equals" relations.)

Hence, I *do* depend on the package providing /usr/share/doc, just
indirectly. Is it really necessary to change the wine packaging, or could
lintian be fixed to not complain about this?
