[Rd] R 3.0.0: wrong MD5 checksums for Windows?

[Henrik Bengtsson]

I can reproduce this (same setup):

> require(tools);
> checkMD5sums(dir=R.home());

It's a '\n' -> '\r\n' issue:

> filename <- "etc/Rconsole";
> md5 <- readLines(file.path(R.home(), "MD5"));
> md5 <- grep(filename, md5, value=TRUE);
> md5 <- gsub(" .*", "", md5);
> print(md5);
[1] "35d6d6cf7957492f78f50c435e36f08e"

> pathname <- file.path(R.home(), filename);
> md5a <- md5sum(pathname);
> print(md5a);
C:/PROGRA~1/R/R-3.0.0patched/etc/Rconsole
       "7436c369255f36aeacca8ab88b5f96c4"
> bfr <- readChar(pathname, nchars=1e6);
> bfr <- gsub("\r\n", "\n", bfr, fixed=TRUE);
> writeChar(bfr, eos=NULL, con="foo.txt");
> md5b <- md5sum("foo.txt")
> print(md5b);
                           foo.txt
"35d6d6cf7957492f78f50c435e36f08e"
> md5b == md5
foo.txt
   TRUE
