[Rd] editor in Windows doesn't like a data frame with row names (PR#797)

[jfox@mcmaster.ca]

The editor in R version 1.2.0 returns an error after editing a data frame 
that has row names. This is on a Windows 2000 system, but I've encountered 
the same problem under Windows 95. Here's a simple example:
