[Rd] package NULL not found

[Prof Brian Ripley]

Note that the message is not about '' and NULL but about '<nl>' 
and NULL<nl>.

I suspect the line endings are screwed up in the environment in use, which 
seems not to be our toolset from the comments about Cygwin.  It is most 
likely the shell used by make that is doing this, but it could be Perl.

I can reproduce this on Linux by

gannet% setenv R_DEFAULT_PACKAGES 'NULL\ 
'
gannet% Rdev --slave
During startup - Warning messages:
1: In library(package, lib.loc = lib.loc, character.only = TRUE, 
logical.return = TRUE,  :
   there is no package called 'NULL
'
2: package NULL
  in options("defaultPackages") was not found

It is what is getting passed to Rterm that seems to be the problem.
