clone --single: limit the fetch refspec to fetched branch
After running "git clone --single", the resulting repository has the usual default "+refs/heads/*:refs/remotes/origin/*" wildcard fetch refspec installed, which means that a subsequent "git fetch" will end up grabbing all the other branches. Update the fetch refspec to cover only the singly cloned ref instead to correct this. That means: If "--single" is used without "--branch" or "--mirror", the fetch refspec covers the branch on which remote's HEAD points to. If "--single" is used with "--branch", it'll cover only the branch specified in the "--branch" option. If "--single" is combined with "--mirror", then it'll cover all refs of the cloned repository. If "--single" is used with "--branch" that specifies a tag, then it'll cover only the ref for this tag.
