Wait, no known conversion from what to what?
If 'string' is a class rather than a typedef, we print "... from
'vector<std::string>...". If 'string' is the bare parameter type rather than a
template argument in the parameter type, we print "... from 'string' (aka
'std::basic_string'...". Either of these styles would avoid printing textually
identical types in the note.
