Rd and guillemots

First of all, thanks to those who've set up R to work so smoothly with
Miktex-- even a total Latex bunny like me got it to work instantly, so
that for the first time I'm able to run my Rd files through the Latex
side of RCMD CHECK.

Now the question/buglet. One of my Rd files contains the following:

\code{mlazy( <<objname1>>, <<objname2>>, <<etc>>)}

When I run the file through RCMD (either RCMD CHECK or Rcmd Rd2dvi
--pdf) the first << and >> are left alone, but the second and third
pairs are converted to single guillemot characters (i.e. European
quotation marks). This inconsistency seems a bit odd.

Yes, this is the tex that gets output:

\code{mlazy( <{}<objname1>{}>, <<objname2>>, <<etc>>)}

This seems to happen in Rdconv.pm, around here:

     ## avoid conversion to guillemots
     $c =~ s/<</<\{\}</;
     $c =~ s/>>/>\{\}>/;


But I don't know enough Perl syntax to tell it to replace all << by 
<{}<, instead of just the first.  (I would have guessed appending a g 
would work, but didn't in a quick test, i.e. $c =~ s/<</<\{\}</g;
didn't 
work.)
