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 Signed-off-by: Vikrant Varma <vikrant.varma94@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
