History expansion is done on a per-line basis, not per-token.  It is performed
before the shell parser sees the line.

At the point the second line is read and history expanded, the parser's state
is still `open single quote', so expansion is inhibited.

I'd rather err on the side of not performing history expansion where it could
possibly be done instead of performing it when it should not.
