Nitpicking: don’t put extra new line: it breaks whole function look.

Nitpicking: after previous check o1->sql and o2->sql are both NULL or not.
So I guess only one check is enough: if (o1->sql != NULL).

Why not simply return strcmp()?

Can you merge this test file with previous one?
I strongly dislike the fact that such simple tests are put in
separate files. Even though we already have sql-tap/alter.test.lua.
