[Rd] Rcmd_environ and R_LIBS_{USER,SITE}

[Dirk Eddelbuettel]

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.
