Not if lazy-loading is used (and it normally is).  But what really is 
wrong with Roger Koenker's suggestion: 'unzip -a' the .zip into a library 
directory?  It will most likely work (the reverse does: zip up on Linux, 
unzip on Windows).

I think that is safe enough in Rd files, as we process the concatenated 
versions.
