[Rd] Minor glitch in building documentation (PR#2371)

[prye@shiraz.apana.org.au]

This is a very minor glitch, which I think is a problem in
texi2dvi. Building *.dvi and *.pdf files fails due to a problem with the
"--texinfo=@set UseExternalXrefs" argument to texi2dvi. This inserts the
additional @set line where it is supposed to, but fails to follow it with a
space or newline, therefore creates a syntax error.


The following patch works here:
