[R-SIG-Mac] R.app intractable history problem

[Rob Goedman]

The 'problem' is that both R.app and R itself save the history file  
(based on their settings). R saves the history after R.app, so if they  
both have the same name it can (and has on a few occasions :-) create  
a problem. Hence my suggestion to Vi to change the R.app name.

R.app will store the history in the file set in the preferences.  
Saving the workspace does not play here. All of this (saving history,  
preferences and optional the workspace) happens on quitting R, which  
is what Vi used to test.
