Well, I explained that I think the "src:dst" way to specify things are not 
meant for git newbies.  Don't use it.

git push <remote> <branchname> works exactly as advertised.  It pushes the 
specified branch to the remote repository.

Don't use src:dest notation.

Don't use src:dest notation.

Use this.  This is good.

Don't use src:dest notation.

Don't use src:dest notation.

Don't use src:dest notation.

Yes.

I hope you return the honour.

Yes, it does.  You no longer can push a tag onto a remote branch by 
accident.  Just don't use the src:dest notation.  Forget about it.  You 
definitely don't need it before you understand git better.
