[issue17980] CVE-2013-2099 ssl.match_hostname() trips over crafted wildcard names

[Tim Peters]

Tim Peters added the comment:

Wildcard matching can easily be done in worst-case linear time, but not with regexps.  doctest.py's internal _ellipsis_match() shows one way to do it (doctest can use "..." as a wildcard marker).
