I'm not sure the \n is really "there" once the file has been loaded into the
editor.
^$
will match a blank line. Replace also works, as long as you specify something
to replace it with. If you leave the replacement text blank, nothing happens.
I think that is the bug. I tested with Kate.
Fortunately linux provides a powerful command line.
cat infile | awk 'BEGIN {RS="\n"; ORS="\a"} { print }' > outfile
will replace unix line ends with \a. BTW I did not have good results with
[\n\a\r]*. It seems to want to match more than just the line end.
