Convenient notation for ignoring "x-and-its-entire-tree"

[ericcornelissen]

Sometimes you want to ignore a dependency and all its dependencies as well(example). The wildcard matcher (*) does not work for this scenario because it only allows for matching (grand)children of a dependency, not the dependency itself. Similarly, using "#ignore" on the top level dependency does not work because that would still report deprecations in its (grand)children.

Both of these are intentional:

• * should not match the dependency itself because it supports the use case of ignoring all transitive dependencies without ignoring direct dependencies.
• "#ignore" should not match transitive dependencies because it supports the use case where you acknowledge a deprecation in a direct dependency but don't necessary want to introduce more deprecations transitively.

I would prefer a solution that introduces an intuitive notation for ignoring a dependency and its entire tree, though I could be persuaded that an "#ignore" directive on a dependency should inherently ignore it's entire subtree.

The outcome of this issue was the following:

• The wildcard * now serves the purpose requested in this issue.
• The wildcard + now serves the purpose of * described in the original issue description.
