Hello,

is there a simple way to specify a non-standard TCP port for a git+ssh
connection? 

The following small patch would allow to use an URL like 
'git+ssh://user@hostname:port/path' to specify an arbitrary 
port for the ssh connection.

Regards
Andreas Jochens

Use the ".ssh/config" file ;)

Maybe. On the other hand, I think we'd be better off  with perhaps some 
way to just specify arbitrary options to the "ssh" program. Sometimes you 
might want to specify identity-files etc too.
