This can be fixed by the patch below that takes into account
the default value `open' of `search-invisible' and treats it the same
as its value `t', i.e. matches hidden text (but it still can't "open" it
in a meaningful way).

I have no idea for a better error message.

This is not a regression, so this patch is intended for trunk:
