    help: add help_unknown_ref() · e5618106
    Vikrant Varma authored
    When the user gives an unknown string to a command that expects to
    get a ref, we could be more helpful than just saying "that's not a
    ref" and die.
    
    Add helper function help_unknown_ref() to take care of displaying an
    error message along with a list of suggested refs the user might
    have meant.  An interaction with "git merge" might go like this:
    
    	$ git merge foo
    	merge: foo - not something we can merge
    
    	Did you mean one of these?
    	    origin/foo
    	    upstream/foo
