Allow to pass port to clone:allow command

[weyert]

If you are running SSH on a different port then 22 this command would fail. I have added the optional argument to pass the port it will fallback to 22 when not given

Looks good though, wondering why this hasn't been reviewed / commented on

Usual reason, not something I need so didn't get round to testing / merging.

To manually test this kind of thing feels like it'd take an age

• Pull his fork to a live server
• Setup a git server on a different port
• try and clone from said git server
• try and clone with passing a port number for a git server on port 22

I mean I could just blindly merge it but that's bound to break the code in a difficult to predict way. I'm not a bash guru or anything so may have missed something.

Another solution to use a different port is to add something to your ~/.ssh/config file eg

Host git.yourhost.com
    Port 2020

Though I can see why it'd be easier to do this on the cli each time.
