R devel - Oct 2012 - Rcmd_environ and R_LIBS_{USER,SITE}

Is there a fundamental reason why I cannot set either one of

  ## add local library path -- doesn't work either
  R_LIBS_USER="c:/opt/R-library"
  R_LIBS_SITE="c:/opt/R-library"

in $R_HOME/etc/Rcmd_environ even though I can seemingly set other things here?

It breaks "R CMD check" for me as I prefer NOT to install packages in
a
versioned path.  

FWIW, defaulting to a versioned path is (to this no-longer-bemused user) as
much a permenent R bug (on Windoze) as the default installation into a path
with spaces.

No reply in a number of hours, so here is a suggestion from ignorance :-}

?Startup refers to a number of other "site and user files to process for 
setting environment variables" but not to Rcmd_environ. The contents of 
$R_HOME/etc/Rcmd_environ seem to reflect (some of) the contents of 
(some) other files.

I have similar lines (defining library paths) in
     $R_HOME/etc/Renviron.site

Is it correct to directly edit Rcmd_environ or should it be modified 
only via other files? (A genuine question).
