[Rd] Bug in sub? (PR#487)

[dtrenkler@nts6.oec.uni-osnabrueck.de]

I suspect that there is bug in sub when using "?":

> string_"This is a bug!"
>  sub("!", ", or isn't it?", string)
[1] "This is a bug, or isn't it?"
> string_"This is a bug?"
>  sub("?", ", or isn't it?", string)
[1] "This is a bug?"


Regards,
