Thanks a lot, Dale, for the quick feedback!

Yes. That is actually another glitch, not at all related to
Windows or even R: Inside "[..]" the S or R version displayed is
sometimes wrong, i.e. the "previous" version instead of the one
that will be taken. 

One thing which *is* Windows-specific is that internally there
are two kind of version names, one being the short 
'R-2.12.1patched-64bit' one, which you also can use via
      M-x R-2.12.1patched-64bit
and the other the full path name (which will be shortened to the
8.3-short path name internally when the *call* to R is made).

I'm about to commit changes which will also fix this glitch,
for R and its available versions at least.
(it will still show wrongly e.g. when calling  M-x S+.. after an
 earlier M-x R).
