Bug#872033: apt edit-sources: missing newline at the end of "file changed, please run 'apt-get update'."

[s3v <c0llapsed@yahoo.it>]

Package: apt
Version: 1.5~beta1
Severity: minor
Tags: patch
Control: found -1 1.4.7


Dear maintainer,

after some changes in sources.list file, "apt edit-sources" sends to output
the message below:

  "Your '/etc/apt/sources.list' file changed, please run 'apt-get update'"

but a missing newline induces the shell prompt to appear on the same line.

 root:~#  apt edit-sources
 Your '/etc/apt/sources.list' file changed, please run 'apt-get update'.root:~#

Please find attached a trivial patch to fix this issue.

Thanks for reading.
