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".) mailing list Received on Tue 14 Oct 2008 - 15:43:14 GMT
