[Rd] splitstr documentation problem (PR#451)

[mcw@ln.nimh.nih.gov]

Using the patched version of R-0.99.0, I cannot reproduce the following
example from the strsplit  documentation:

(Example)
unlist(strsplit("a.b.c", "."))  
## [1] "" "" "" "" "" 
## Note that `split' is a regexp!  
## If you really want to split on `.', use
unlist(strsplit("a.b.c", "\."))
## [1] "a" "b" "c"

The problem is in the second example; the "\." should be "\\."  

Thanks for the great software.
