D'oh.

I've just spotted this, I guess there's a hard thing to do then. If
you match 'SELECT' then you miss the lower case version - but if you
match both there are often multiple false positives.
The other thing is that my current approach is single-line only, so
multiline SQL statements are liable to be missed - I guess if anything
this suggests real parsing is the correct approach.
