[Rd] Row subsetting of data frames (PR#425)

[plummer@iarc.fr]

If you want to use row names to take a row subset of a data.frame then
there is a bug when
- One row has a name which is a completion of another row name
- The shorter name comes after the longer one
- You want to retrieve the row with the shorter name

An example:

R> x <- matrix(1:4, 2, 2, dimnames=list(c("abc","ab"), c("cde","cd")))
R> x
    cde cd
abc   1  3
ab    2  4
R> x["ab",]                       #Works OK for matrices
cde  cd 
  2   4 
R> y <- as.data.frame(x)
R> y["ab",]                       #but not for a data frame
    cde cd
abc   1  3
