 // A pattern that can be used to match URLs. A URLPattern is a very restricted
 // subset of URL syntax:
 //
 // <url-pattern> := <scheme>://<host><path> | '<all_urls>'
 // <scheme> := '*' | 'http' | 'https' | 'file' | 'ftp' | 'chrome'
 // <host> := '*' | '*.' <anychar except '/' and '*'>+

add a mention of the <port> here, that explains when it is allowed

[Bernhard Bauer, 2011/06/28 16:46:31]

Done.

 // <path> := '/' <any chars>
 //
 // * Host is not used when the scheme is 'file'.
 // * The path can have embedded '*' characters which act as glob wildcards.
 // * '<all_urls>' is a special pattern that matches any URL that contains a
 //   valid scheme (as specified by valid_schemes_).
 // * The '*' scheme pattern excludes file URLs.
 //
 // Examples of valid patterns:
 // - http://*/*
