[Bug 3935] [FT] Section 3.2.7: Escaping wildcards

We do not have escaping syntax for wildcards. We did not consider this an
important use case, since the characters used for wildcarding are not likely to
be searched and many implementations will choose not to support searching them.
If you have a query where you want to search for such characters and want to
use wildcards as well you would need to split query terms apart to be able to
use "with wildcard" and "without wildcard" as appropriate. E.g. if you want to
match * literally in "A*B.{2,3}C*D" you could write:

("A*" without wildcard) && ("B.{2,3}C" with wildcard) && ("*D" without
wildcard) 
distance at most 0 ordered

If you think escaping wildcards is important we have to reopen the discussion.
