Comment:

 Thank you for the report and patch, @JPry!

 I was thinking about this, but we don't really need to make the change,
 for two reasons:

 - `!` is a special character that `preg_quote()` already escapes.
 - `!` isn't a character that PHP allows in stream names, so if it shows up
 in `$wrappers`, things have gone horribly wrong.
