[Rd] Please make Pre-3.1 read.csv (type.convert) behavior available

[Tom Kraljevic]

Hi,

We at 0xdata use Java and R together, and the new behavior for read.csv has
made R unable to read the output of Java’s Double.toString().

This, needless to say, is disruptive for us.  (Actually, it was downright shocking.)

+1 for restoring old behavior.

Thanks,
Tom
