I read in the bible (https://www.eff.org/https-everywhere/rulesets) that:
"""
To cover all of a domain's subdomains, you may want to specify a
wildcard target like *.twitter.com. Specifying this type of left-side
wildcard matches any host name with .twitter.com as a suffix, e.g.
www.twitter.com or urls.api.twitter.com. You can also specify a
right-side wildcard like www.google.*. Right-side wildcards, unlike
left-side wildcards, apply only one level deep. So if you want to
cover all countries you'll generally need to specify www.google.*,
www.google.co.*, and www.google.com.* to cover domains like
www.google.co.uk or www.google.com.au.
"""
The previous interpretation is both incorrect (because right wildcards
only apply one level deep) and potentially expensive (regular
expression matching is exponential in the worst-case.)
