I don't think that the ess "make install" created the file, rather that the "apt get" 
process I used to install an earlier version of ESS from the xubuntu repository created 
it.  How or why I can't say.  It wasn't a bug for ess to track or fix, just a heads up wrt 
a question you might get from others one day.  That is why it was listed as a footnote to 
the main question.

I don't doubt that the annoying behavior has been there for years.  I'd like someone to 
fix it.
I write in noweb/Sweave/knitr for clarity of documentation, with human readers as the 
target.  Rewriting code in a less obvious form just to please a text editor is the wrong 
approach.
