[ESS] ESS and .Rhistory

[Yihui Xie]

OK, I see. It will be great if ESS does not drop the .Rhistory bombs
under every single directory in which I start R :-)

I also noticed another issue which also involves with ESS ignoring the
configuration, and I will report in a separate email.

Thanks!

Regards,
Yihui
