help: add help_unknown_ref()
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
