Not too much. However it has some benefits, for example it will
auto-page as usual and the pager is run locally which the ssh line
above wouldn't do of course...

Also, "-H" allows you to do stuff such as "-H foobar:waldo:quux" which
means we'll talk to host "foobar" and then its container "waldo" and
the container "quux" nested into that...
