[R-SIG-Mac] Can't save history using savehistory()

[Ken.Williams at thomsonreuters.com]

Hi Rob,

It appears that the file is being written to .Rhistory in the working
directory, but *I think* it reads from ~/.Rhistory in my home directory.
In my preference pane I've got it set to read from ~/.Rapp.history, so
that's 3 different files.  That last file seems to always be empty.

Here's my plist file (converted to text):  https://gist.github.com/798719

When you suggest renaming the file & starting over, which of those 3 would
you suggest?
