[issue8572] httplib getheader() throws error instead of default

[Walter Woods]

Walter Woods <woodswalben at gmail.com> added the comment:

David: Your example tests specifically for a string, but what about just converting default to a string always if it's not a list?  Otherwise the string join is just going to fail anyway (suppose an integer is passed, which is the case with couchdb-python).  Wouldn't


if not isinstance(default, list):
    default = [str(default)]

Be safer?
