I have not tried emacs. I originally edited the files with nano. But later
in order to get rid of that trailing blank line I used vim, nano, gedit
and mc. Only in mc I was able to eliminate it. However, the server where
the files are does not have mc (installing it is not an option). With
gedit I see that there's an empty line at the end, I delete it, save the
file, but when I reopen it, it's there again.
So I am still puzzled.
