I thought I had checked for missing no-* options but apparently I missed
those.  These might even be 6.3.X stuff depending on how complex the fix
will be in code, I will check that.

I have always wondered if we should be adding some notion of scope to
settings, but this would then have to go along with parenthesizing
(perhaps using curly braces) of some form, perhaps apply defaults ... to
... end defaults statements.

Sooner or later I will have to rewrite the bison parser because it
invariably must leak memory and has some minor quirks, but have not
decided on a solution.

Lemon (from sqlite3's author) is one option, going for C++ with
Boost::Spirit that follows a strict full resource tracking through
objects is another, and there are surely more solutions.

This will entail a parser rewrite and might be a good point in time to
specify such extensions.

(Bison recommends to consider garbage collection, but I'm not sure that
it's the right approach, it can lead to apparently nondeterministic
timing behaviour.)

Thanks for your suggestions!
