There's plenty of space for creating pathological commands. Do you
want another one?

"select * from blah limit%s"

I think in general sticking characters in front of placeholders you
don't know how will get filled is not a robust way to write your sql
string.

I'm -1 about complicating the escaping of simple values just to
accommodate artificial problems: fixing this one IMO wouldn't justify
the potential problems of backward incompatibilities that may arise.
