Section 2.4 (Extensions to Static Context)

Is there any reason not to change FTOptionDecl to accept FTMatchOption*
(instead of singleton FTMatchOption)?

That is, allow this:
declare ft-option diacritic sensitive case sensitive;

It is a small usability point, but it seems to me that these will usually come
in bunches, and having something look more like the options in the query itself
is a good thing.
