Option to not auto-find matching alternative command

[rudiedirkx]

To allow an application subclass to disable auto-find matching alternative command.

I see many developers type namespace: to see what commands are in the namespace namespace, instead of list namespace, because it's easy, because it's closer to the real thing you type to execute the command. But also dangerous, because if the namespace has only 1 command, it's auto executed, without any notification. This option disables that, IF the app developer wants. Some people like or need less magic.

Thanks for your pull request! We love contributions.

However, this repository is what we call a "subtree split": a read-only copy of one directory of the main Symfony repository. It is used by Composer to allow developers to depend on specific Symfony components.

If you want to contribute, you should instead open a pull request on the main repository:

Thank you for your contribution!

PS: if you haven't already, please add tests, and beware that bug fixes should be submitted on the lowest maintained branch where they apply; only features should be submitted against the master branch.
