[Rd] documentation bugs (cvs) (PR#5543)

[maechler at stat.math.ethz.ch]

Thank you, Brian.
I've just committed the fixes.

Apropos the one in paste.Rd :

 \value{
   A character vector of the concatenated values.  Thus will be of length
+% objects are (....) unless ???
   zero if all the objects are unless \code{collapse} is non-NULL, in
   which case it is a single empty string.
 }

I've just added a "," between 'are' and 'unless' -- Do you
understand it now?
