branch: deprecate --set-upstream and show help if we detect possible mistaken use
This interface is error prone, and a better one (--set-upstream-to)
exists. Add a message listing the alternatives and suggest how to fix
a --set-upstream invocation in case the user only gives one argument
which causes a local branch with the same name as a remote-tracking
one to be created. The typical case is
git branch --set-upstream origin/master
when the user meant
git branch --set-upstream master origin/master
assuming that the current branch is master. Show a message telling the
user how to undo their action and get what they wanted. For the
command above, the message would be
The --set-upstream flag is deprecated and will be removed. Consider using --track or --set-upstream-to
Branch origin/master set up to track local branch master.
If you wanted to make 'master' track 'origin/master', do this:
git branch -d origin/master
git branch --set-upstream-to origin/master
