commands: pass include and exclude options to hg.clone() These arguments are defined by the narrow extension. Let's teach core to recognize them so we can delete some code from the narrow extension and start to exercise the in-core code for performing a narrow clone. We have no way of easily testing it, but this change should result in .hg/requires having the narrow requirement from the time the file is written rather than added as part of pull. We'll confirm this when we delete some monkeypatched functions from the narrow extension in later commits. Test output changed because hg.clone() is now receiving patterns and validation of those values is occurring sooner, before the exchange code runs and prints the message that was deleted.
