It was pretty easy for me to get these line endings -- I created the file in GNU Emacs under Windows, and rsync'ed the package directory to a Ubuntu Linux machine. I went back and checked, and GNU Emacs under Ubuntu did show (DOS) in the status line of the buffer, but I never noticed that while I was trying to figure out why my .Rbuildignore file wasn't having any effect. (I think I preferred it when Emacs would show ^M at the end of each line in a CRLF file -- not showing that is what I meant by "hiding it from me".)
In the Splus package system INSTALL copies the whole package directory to a temp directory before doing any other processing. If it sees a 'text' file, as determined by the perl -T (or ! -B) file test operators, the copied file will have local line endings. We don't use cygwin in the Splus package system, so what the local line ending is is clear. (Copying the entire directory also means we can run INSTALL on a read-only package directory and we don't leave around *.o or *.obj files that R CMD INSTALL won't like).
