Re: [Ltru] * in extended filtering

Ignored is probably the wrong word. The sentence really means: "[t]his 
is the reason why a wildcard in the extended language range is only a 
significant difference in the first position but whose inclusion (or 
omission) has no effect elsewhere in the range."

Step 1 says, "Two subtags match if either they are the same when compared case-insensitively or the language range's subtag is the wildcard '*'." Steps 2 and 3 refer to subtags "match[ing]", where "match" is defined in step 1, and these steps apply only to non-initial positions. Step 3.A also makes explicit reference to "*" in the range subtag -- again, this being non-initial subtags.
