Feature request: exclude patching by directory, not namespace

[adamcameron]

Currently I can exclude namespaces to patch via:

$this->commandLine()->set('exclude', [
    'com\example\someapp\etc'
]);

However what I want to do is exclude the vendor directory entirely. I even think that's probably a more common use-case requirement for excluding? Dunno.

A similar argument could be made for the include option, I think.

It's not a big problem for me in the bigger scheme of things, as I can just include my own namespace, and that "should" work.
