[Rd] Set Repositories problem in R2.4.0

[Prof Brian Ripley]

The point is that there is no `read.table' line in setRepositories, just 
read.delim.  And the NEWS for R-devel (there is no 2.4.0 yet) says

    o	The functions read.csv, read.csv2, read.delim, read.delim2 now
	default the comment.char argument to "".  (These functions are
	designed to read files produced by other software, which might
	use the # character inside fields, but are unlikely to use it for
	comments.)

It needs the person who made that change to fix the consquences: thank you 
for altering us.
