Hmm. What about this case? Package P is linked against library
package L. L has a bug which is fixed starting at a certain version, but
doesn't require an ABI change.

Since L doesn't change its ABI, does it need to change its shlibs?
Yet P might want to specify that it requires a certain version of L.

Depends: ${shlib:Depends}, L (>= blah)

results in duplicate dependencies, which lintian says is bad. (I'm not
sure why it's bad though.)

This happened with Xpdf and libt1-5 recently.
